@gary-kim Should I try it by changing the specific files myself? The build didn't finish so 0.8.1 is not released.

The continuous integration system doesn't make a new version per PR.

You can try installing it using the README installation instruction: https://github.com/gary-kim/riotchat/blob/master/README.md#installation

I tried changing the files manually but I can't find the .js files (probably compiled?).
Would be easy for you to just compile it and paste it here as a tar.gz or so?
Otherwise, I try it on another server to compile (want to keep my production server clean).

@gary-kim I did the following

git clone https://github.com/gary-kim/riotchat.git
cd riotchat
git checkout fix/380/delete-on-logout
git pull
git submodule update --init --recursive
make

und nach make kommt folgende Fehlermeldung:

(cd 3rdparty/riot-web && rm -rf ../riot && yarn && yarn add @nextcloud/browserslist-config && yarn build && cp config.sample.json webapp/ && cp element.io/develop/config.json webapp/develop.config.json && git describe --exact-match HEAD | cut -c 2- > webapp/version && mv webapp ../riot && yarn remove @nextcloud/browserslist-config) || (cd 3rdparty/riot-web && yarn remove @nextcloud/browserslist-config && exit 1)

make: *** [Makefile:17: 3rdparty/riot] Fehler 1

Fehler 1 means Error 1

Tried to access it anyways, but it just shows a blank page.

I am using nextcloud-fpm docker container, so it is installed unter custom_apps. I stopped the container before installing it and starting the container after.

Same happens with the master branch, I installed yarn, npm, node-js, make.

Looks like you have the wrong Yarn:

Okay, I'll merge this for now.
