Admin panel cannot be loaded

[Celerii]

Describe the bug

I cannot manage to reach the admin panel : when I input the URL specified by the "administrator docs" section ("https://emrys-vision.fr/snappymail/app/?admin", I get the following error message: "An error occurred. Please refresh the page and try again. Network response error: 500".

This is a very recent problem that is not resolved either by reinstalling the app or even completely rebuilding my VPS server. I have installed SnappyMail on Yunohost many times already, and I never got this problem until yesterday.

What I have already tried:

• Using another browser
• Connecting from another IP address
• Moving the app to its own subdomain
• Reinstall the app
• Rebuild the server from scratch

I have activated Level 7 logging and this is the only thing I can see in the log file:

Misc remarks:

• My domain settings are OK and Yunohost diagnostics only exhibit minor and unrelated warnings
• The client side of the app works normally, only the admin panel fails to load
• Changes made in the application.ini file are taken into account

Context

• Hardware: VPS at OVH
• YunoHost version: 11.2.10.3 (stable)
• I have access to my server: SSH + webadmin + online KVM at OVH
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
  • If yes, please explain: I use a typical install, either in a subdomain or not
• Using, or trying to install package version/branch: only using the Yunohost store
• If upgrading, current package version: 2.35.2~ynh1

Steps to reproduce

• Install the app through the Yunohost store
• Try to launch the admin panel through the provided URL

Expected behavior

The admin panel should be displayed.

Hi there,

I just made the update to the 2.35.4~ynh1 version of SnappyMail, and the problem is now gone: I can access the control panel and make changes.

A big thanks to whoever managed this issue! 👍
