@necrevistonnezr The 500 indicates some error but the logs itself don't have any error. Can you check /tmp/roundcube/logs using the Web terminal ?

Is it possible you have a plugin that doesn't support PHP 8? That was only major change in 2.7.1

[necrevistonnezr]

@girish Indeed, it's the CardDav plugin (https://github.com/mstilkerich/rcmcarddav) - which is a real problem because what good is an email client without an address book?
It shows again to avoid apps that rely too much on a plugin system (i.e. Nextcloud). Core functionalities need to be built in and supported.

EDIT: I had installed the plugin by pulling the current repo to the plugins folder - looks like this does not work anymore. Manually installing the CardDav plugin via the release tarball works.
This is solved.
