App Page not available after Upgrade to 15 Beta 2

[Nils160988]

Steps to reproduce

1. Log in to your nextcloud with an account with administrative privileges
2. Click on "Apps" in the right hand menu
3. Blank page appears (only the header is visible)

Expected behaviour

See the usual page with all apps and options to disable, install, remove ... apps

Actual behaviour

Nothing on the page

It worked with Beta 1. If necessary, I can do further test and provide logs.
Help will be appreciated.

@Nils160988 Could you check the web browsers dev tools for errors? Typically you can open them in any browser with F12.

[Nils160988]

Indeed, there are some errors:

Interestingly, I checked with another Laptop and could access the page without problems (same browser!). Does this information help?

Edit: "Users" panel is also not working.

[MorrisJobke]

@Nils160988 Just to confirm: This is happening for you in Firefox 63? Could you check with Chrome/Chromium? Could you clear the browser cache and load the page again?

This then sounds like a caching issue. @juliushaertl Any idea why the cache busting should not work?

[skjnldsv]

Data from server are the same, so yes, clearing cache seems like the issue here.

[Nils160988]

Clearing the cache helped for me.

Not sure if this information helps: I am using multiple nextcloud accounts (test.DOMAIN.de and DOMAIN.de) on this laptop. Is it possible that this has to do with the issue?

[skjnldsv]

It should not. Only the browser cache would make a difference here :)
