Works fine here using Nextcloud 11 and 12 with Chrome 55

Looks like some JS goes wild. This is also the page with already installed apps. Mmmmh. Is there anything in the web developer tools console in your browser?

[annando]

I will have a look at it when I'm back at the clients again that are making these problems.

[annando]

I know what caused the problem: I'm using the "Binnen-I be gone" extension in chrome. This causes the problem.

Do you have any further details what this extension actually broke? Has it replaced some code on our side or what was going wrong there?

[annando]

"Binnen-I be gone" is a script that changes the content of a page. It normalizes the different forms of "Binnen-I", "Gender-Gap", "Gender Star" and their different variations.

I guess that somewhere in the nextcloud javascript code that is responsible for displaying this warning, there is a text that was falsely replaced by this extension.

[nickvergessen]

The extension replaces canInstall with canstall and canUnInstall with canUnstall in our ajax responses, so our checks don't pass anymore...

This is a really funny issue. 😂
