Update to 1.5.2 from 1.4.11 gets internal server error

[Avian2]

I have Roundcube installed on Ubuntu 20.04.3 LTS, with all updates. When I upgraded from 1.4.11 to 1.5.2 tonight, I get an internal server error. When I switch back to 1.4.11, the error goes away. When I look at the errors.log file, it seems to be complaining about missing classes: Spoofchecker and rcmail_oauth.

Code: [Select]

Has anyone else encountered this? How do I fix it?

Thanks,

Since version 1.5 the php-intl extension is now required as part of your PHP setup

Thanks - I'd enabled it in php.ini, but didn't realize it wasn't installed. Sudo apt-get install php7.4_intl installed it and all works now.

Thanks!
