plug in not configured or QGIS master password not set up

[jakub-f]

User opened QGIS 3.22 to his default profile. Mergin says not configured. Clicked test connection. Mergin update all is good.
Switched over to new profile created, from below. Mergin says not configured. Clicked test connection. Mergin now says “plug in not configured or QGIS master password not set up”.

We have several user with this problem at the moment. Unable to get the plugin it working at all.

We've encountered this problem, too. We are on QGIS 3.34.6 and Mergin Maps 2024.2.1.

We fixed the issue via the following steps:

• Uninstall Mergin plugin

• Go to Settings > Options > Authentication and delete the entry for Mergin in the configurations

• Restart QGIS

• Reinstall Mergin Maps plugin

• Browser widget shows "Double-click to configure"

• Configure (as an unrelated point, "Custom Mergin Maps server" is checked by default. Is that correct?)

• Test Connection - returns OK

• Ensure Save credentials is activated

• Press OK

So it seems like the fix was to both reinstall the plugin and to remove the password from the QGIS authentication database. Just reinstalling the plugin didn't fix it. The instructions for removing the password came from this issue: #48 (comment)

Unfortunately, I don't know how we got into this situation in the first place, so I can't create a reproducible example.

I hope that this helps someone else with the same problem.
