Hey @punkyard, which version of Nextcloud 28 do you run? We fixed issues with duplicated content in Nextcloud Text with the 28.0.5 release. If you still run 28.0.4, upgrading might help.

[punkyard]

Hello @mejo- here are the correct versions of my apps:
NC AiO 8.2.1
NC 28.0.5
Collectives 2.11.0

[mejo-]

@punkyard could it be that the duplicated content originates from an editing session that was still with Nextcloud 28.0.4? We're aware of this duplicated content problem with Nextcloud 28.0.4, but I really hope we fixed it with 28.05. So it would be important to know whether this is still reproducible for you with 28.0.5.

[punkyard]

this woud be hard to tell, maybe. If the doubling doesn't occur again, then it's perfect ^^ so far, so good.

[mejo-]

Perfect, then let's wait a few more days and I'll close the issue if I don't hear from you again. Please report back if this happens to you again 😊

[nunoleite]

Hi!
Nextcloud 27.1.9
Collectives 2.11.0
I'm having this problem too.
Just opening and viewing a collective, the content shows repeated.

I'm still on version 27.1.9 (waiting for the app News to be compatible with 28).
And i just opened a collective minutes before i sent the message.

[sen4git]

Hello,
I just started with collectives as a wiki for teachers of a high-school and encountered the same effect, that some collective-sites have doubled content (text and pictures).
That was on version 25.
After update to version 28 the problem still remains.

It is related to problems with "unsaved changes" of the collective-site.
Unsaved changes are indicated by a little blue dot under the tick (to save the site).

The unsaved-changes-problem is even bigger than the doubled-content-problem. I encoutered it on multiple but not all sites:

• I clicked the tick to save a collective-site (that includes pictures) and everything looks fine.
• Sometimes I encounter that a normal user (without rights to change the collective) doesn't see the pictures an that site but a broken link.
• When I check that site, the tick with the blue dot indicates that there are unsaved changes of the site. I repeated saving the site but the site remained with unsaved changes - after some minutes .....

I worked around:

• Opened that site in the files-app
• AND IN THE FILES-APP THE CONTENT OFTEN APPEARED DOUBLED !!!
• I removed the doubled content in the files-app and saved the site in the files-app => OK (in most cases)

Hope that helps targeting the source of the problem.

Thanks for your work!!!

[sen4git]

PS: The unsaved-changes-problem really appears often and we have to check all new or updated sites with a normal user-account (without rights to change the collective) after 10 minutes for broken links to pictures...

[sen4git]

PPS: We are on version 28.0.3

[punkyard]

hi @sen4git
for how long have you been using Collectives for publishing courses?

We have used it for two years - but we stopped. Too much time and effort to work with. Plus new functions we didnt like, that are not options.

We have moved to a mix of markdown and direct publishing, with Compiiile and Logseq (very useful to project in class)

[mejo-]

Dear @sen4git, as mentioned above the issue only got fixed with Nextcloud release 28.0.5. You encounter this issue because you still run Nextcloud 28.0.3.

[sen4git]

Hi punkyard,
thanks for the tips. I'll take a look on them. We will stick to collectives as wiki, because we need an nextcloud-integrated wiki.

Hi mejo,
thanks - I hope that the related "unsaved-changes-problem" with the broken links to pictures will also disappear with 28.0.5.

[estux]

Dear @sen4git, as mentioned above the issue only got fixed with Nextcloud release 28.0.5. You encounter this issue because you still run Nextcloud 28.0.3.

@mejo- I just encountered a similar issue (rendered duplicated text) on Readme.md preview (folder description) above file list in a folder. I'm running 28.0.5. Should I report this to server repo or Text repo? Thank you very much!

[max-nextcloud]

I just encountered a similar issue (rendered duplicated text) on Readme.md preview (folder description) above file list in a folder. I'm running 28.0.5. Should I report this to server repo or Text repo? Thank you very much!

Could you check if the file actually contains the duplicate content? If it does, could you check if there's a version in which it was introduced and if that happened when 28.0.5 had already been deployed? Thanks!

Hello @max-nextcloud I downloaded the .md file to check (not opened it first in the online editor). The file doesn't contain the duplicate content. Then I tried to open the Readme.md in the online editor and instantly the doubled content was written and saved in the file permanently.

This seems to happen only with Readme.md files as I tried to open other .md files and also the Collectives editor and the duplicated content bug doesn't seem to happen.

[br4yd]

Fyi I had the same issue happening with all my notes in the Nextcloud Notes app after upgrading to 28 and then 29.

[mejo-]

If this happens to documents that you open the first time since longer, this might be because there is still an outdated session from before the upgrade for this document stored in the database.

If you open a document for the first time since the upgrade and experience duplicated content, you could check the following:

• Download the markdown file and see if the duplicated content is there as well
• If that's not the case, run php occ text:reset <file_id> and reload the page. The duplicated content should be gone

For documents that have been opened and closed in the meantime, you probably have to fix them manually. Sorry for that.

[mejo-]

And please continue reporting cases where this happens!

For now our understanding is that this happens for old documents with an editing session from before the upgrade to 28.0.5 (or 27.1.9) when they get opened again for the first time.

Particularly interesting would be cases like the following:

• Duplicated content in a file that for sure only got created after the upgrade
• Duplicated content again in a file that already had been opened since the last upgrade and cleaned up

Hello @mejo- I'm sorry to bother but I think I have to report another case as it's hitting my server quite randomly (apparently).
Just a note: this is related to duplicated content in general and not directly related to Collective. I hope it's still the right place to let you know as you pointed out.

I have some Readme.md and Leggimi.md (some of them apparently generated with the name translated in italian as my laptop uses the IT language). All of them are files used for folder descriptions as the name implies.
This morning (some minutes ago) I was just navigating the folder tree to see what's the content of some folders and when I entered a folder with a Leggimi.md created on 13/12/2023 it immediately (and alone) modified the file and I saw duplicated content in the preview-description above the files. I saw immediately this problem because of modified timestamp when I was coming back to the previous folder. So I downloaded the file and checked that the duplicated content was just also written in the file by the system.

The same problem happened yesterday evening with a Readme.md file (older, untouched from 2021) modified by the system just navigating the folder which contains it.

So apparently there's no difference in behaviour between Readme.md and Leggimi.md files.

I checked the exact timestamp on nextcloud.log to see if some errors are registered but I'm just seeing this:
{"reqId":"m03dD94WpK44zooFwEWF","level":1,"time":"2024-06-06T13:14:06+02:00","remoteAddr":"myIP (sensitive)","user":"name of the user(sensitive)","app":"text","method":"PUT","url":"/apps/text/session/209277/create","message":"Keep previous document of 209277","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0","version":"28.0.6.1","data":{"app":"text"},"id":"66619b1a8aa4f"}

Thanks @estux. As mentioned earlier, the problem is two-fold:

• Affected files likely still have old steps from before the upgrade stored in their editing session. That's why it's important to reset the editing session by running occ text:reset -f <file_id> for these files.
• If the duplicated content did not get persisted yet to the markdown file, the duplicated content should be gone after resetting the editing session with the command from above.
• For files where the duplicated content got already written to the markdown file, you'll have to clean it up manually once, but still should run the reset command for these files.

We understand that this is unexpected behaviour and an inconvenient bug. We're currently working on a fix to reset all old editing sessions with the upcoming Nextcloud bugfix releases.

Hello @mejo- thank you for the detailed answer!
Sadly I cannot do this step (even if I would know how to do) because I'm using Nextcloud by a provider without SSH access and without root access. So I would need to comunicate all the files names to my provider to act on them (even if practically it could already know them as the server is not encrypted). Thank you the same, I think I can only wait for the update.
