Avatars plugin: Call to undefined function mime_content_type()

[yasuhirokimura]

After updating Avaters plugin to 1.12, 'Unknown error' is diplayed as following when listing messages in folder.

And follwing messages are written to log file.

The problem disappears by disabling Avaters plugin.

I have following 2 instances of SnappyMail.

Instance 1

• FreeBSD 13.2-RELEASE amd64
• Dovecot 2.3.21
• Apache HTTP server 2.4.58
• PHP 8.3.1
• SnappyMail 2.32.0

Instance 2

• Debian 11.8 amd64
• Dovecot 2.3.13
• Apache HTTP server 2.4.56
• PHP 7.4.33
• SnappyMail 2.32.0

And the problem only happens with the former.

Fileinfo is enabled by default. Somehow it is disabled in your PHP instance. https://www.php.net/manual/en/fileinfo.installation.php

Can you check that?

@the-djmaze In FreeBSD Ports Collection fileinfo is provided as separate port. I installed it and now the problem is fixed. Thanks!
