App Links missing

Support intro

This is bizarre but I have lost access to apps along the navigation bar. I currently can see Dashboard, files, photos, activity. Nothing else. When I search for an app say music it says it is installed but is not showing in the navigation menu and it says that it is version 0. If i disable the app then download and enable it then reappears in the menu and in the case of music returns all my settings. I reinstalled calendar, contacts and mail but each version still shows as 0.

Nextcloud version (eg, 18.0.2): 20.04
Operating system and version; Linux 4.15.0-88-generic x86_64
Apache or nginx version (eg, Apache 2.4.25): ???
PHP version (eg, 7.1): 7.3.15

The issue you are facing:
As above apps missing from menu and showing version 0

Is this the first time you’ve seen this error? (Y/N):

Steps to replicate it:

Unfortunately I don’t understand what you want to tell us. Can you please be more precise, describe in detail what exactly your problem is and provide a step-by-step description how to reproduce your problem. It might also be helpful to provide a screenshot showing what you’re missing.

The problem with providing a screenshot is that I think I have sort of fixed it.

When ! log into Nextcloud, at the top of my screen is the following menu:
Screenshot from 2021-01-10 17-21-02|645x157

Although I have managed to add into the menu some of the missing apps when I logged in 1 hour a go the top menu was showing only four app icons. I went to settings - apps to see if I could work out why they were missing.

The above screenshot shows where I navigated to. I looked for Music because that was the one I noticed missing but it did not show in my list of apps installed, so I did a search and when the music app showed in that search it had the word disable next to it which showed it was installed but the app version was 0.

I disabled the app and then re-enabled the music app and it came back. So I have my music app back but other apps missing so I went looking for other apps that were missing and I think I have found some but not all. I’ll keep looking but it looks like this is solving it however it seems like something was wrong and that is why I posted here.

I hope that helps.


Ok, it might be possible that the apps have been disabled during a Nextcloud update. In this case you need to re-enable it one-by-one.

BTW, I think the displayed PHP error has nothing to do with the described problem. You should try to search the forum for a solution, like e.g.

Thanks for the help, it did happen after an upgrade.
