You can still edit it.

Would you mind defining “we don’t really know how it works”?

I have found that instances that do seem to modify the source code just use the existing “Code” link and simply point it to their own repo instead.

I use Nextcloud’s Calendar to sync to other calendar apps over CalDAV.

occ files:scan --all (or something like that)

I have already done this, as was mentioned in the post.

I enabled that in /var/snap/nextcloud/current/nextcloud/config/config.php with 'filesystem_check_changes' => 1,, but it did not fix the issue. It did seem to remove one error that was popping up, but I am still getting a prompt stating that the file could not be created (which is strange because, when I did a file scan, it shows that they were created), and the files are still not displayed.

It should also be noted that I restart nextcloud after applying the changes with # snap restart nextcloud.

Tried this. Still nothing.

for example to 777 as a temporary solution

Just tried this, and still nothing.

# chmod -R 777 data-directory
