Cannot edit user from backend...

After migrating the data from a Joomla 3 installation of Community Builder into a Joomla 4 installation of Community Builder I am experiencing some strange anomalies.

When attempting to open/edit a user record from the backend I get this error - 0 readdir(): Argument #1 ($dir_handle) must be of type resource or null, bool given.

Can you give me some guidance as to how to correct the problem(s)?

Migrate data? You mean you moved data via database or did you simply upgraded a Joomla 3 install to a Joomla 4?

I migrated the data from the Joomla 3 database to the new Joomla 4 database using SP Transfer.

Then I've no clue if that data was migrated properly or not as we're not the developers of SP Transfer. Enable debug mode and maximum error reporting in Joomla global configuration then retry and provide the full callstack of the error so we can see where it's coming from.

Ideally when doing a migration from existing install to fresh it's best to make sure they're both on the same versions. So for example the below would be my process.

1. Backup Joomla 3 install
2. Backup Joomla 4 install
3. Make a clone of Joomla 3 install
4. Update CB and all its plugins on Joomla 3 clone
5. Update Joomla 3 clone to Joomla 4
6. Manually move database data from Joomla 3 clone (now on Joomla 4) to fresh Joomla 4

That should give you a safely migrated database of data, but database data migrations requiring moving a lot of things to ensure users transfer over. Joomla users for example are stored in _users and have associated usergroups mapped to them, etc.. that also need to be moved or they lose their usergroups.

I have done this many times with no issues. The View Profile menu item works well but the Edit Profile menu item does not. Here is the info after selecting a user to edit.

An error has occurred.

reddir is failing. Either the following directories don't exist or are not writable.

/images/comprofiler/gallery/canvas
/images/comprofiler/gallery

If you supplied a custom gallery directory path in your image field then you need to check that that path exists and is writable. Edit your image fields to find out what gallery path was supplied.

The most likely culprit is you migrated data only and didn't migrate the files. So you need to migrate the following folder to your new Joomla install as well.

/images/comprofiler
