After update to 2.34.1 it keeps loading

[lancos]

Describe the bug
With nextcloud 26.0.11 and SnappyMail 2.33 all works fine as expected. After upgrade of SnappyMail app to 2.34.1 Nextcloud can't load SnappyMail app anymore, the page loops forever with a blank page with SnappyMail text in the middle and a spinner animation.

To Reproduce
Upgrade the SnappyMail App to latest version 2.34.1

Expected behavior
I expect that snappymail page will be loaded

Screenshots

Please complete the following information:

• Browser: Firefox 122.0.1
• IMAP daemon: extenal IMAP server
• PHP version: 8.1
• SnappyMail Version: 2.34.1
• Mode: nextcloud 26.0.11

And with Nextcloud 28.0.2 Snappymail puts Nextcloud into maintanence mode and made it totally unusable. So in order to use Nextcloud again I had to remove Snappymail. I remember something similar had happnened before.

And with Nextcloud 28.0.2 Snappymail puts Nextcloud into maintanence mode

That is not related. See #929

Nextcloud can't load SnappyMail app anymore, the page loops forever

Open your browser developer tools and see what the error is.
Else check logs https://github.com/the-djmaze/snappymail/wiki/FAQ#how-do-i-enable-logging

Same issue here. Snappymail loads forever. There is no error in dev tools. Since it is reloading forever, I am not sure what I am looking for before the page reloads. I turned on the logs and went looking for the logs on Nextcloud. You should update your page to include the correct location for the logs on Nextcloud.
Anyway.
That's what I saw:

Note: see the crash in the log....
Note2: I think it loops forever because I use the autologin in the nextcloud setting. So I turned it off and logged in to IMAP manually on the snappymail login page and it sent me right back to snappymail username password. So, as logs show, something is crashing while enumerating some folder or messages after connect.
Note3: Since my users use this for their daily mail, that's very bad for me. And there is no option to revert back to earlier version

@jmrapin81 see #1438

[jmrapin81]

@the-djmaze thanks. That worked.

It is worth mentioning that, in order to disable namespace, once in the admin > domains, for each of the domains defined, you need to:
click on the test button,
fill in a valid username and password,
and only then will NAMESPACE keywork show in the list. Tick the NAMESPACE keyword to disable it.
And save.

Took me a while to realise this.

@jmrapin81 is just wrote a wiki page for it 😉

@the-djmaze, thanks. I confirm disabling NAMESPACE works even for me.
