I tested UNA 12 on php8 but didn't work for me. I always get a blank page with error "allow_url_include is on (you need to disable it, or your site will be unsafe)", no matter if module is disabled, still gives the same error.
Hi I noticed that same problem "allow_url_include is on (you need to disable it, or your site will be unsafe)" when updating PHP on our server. The default php went from ver.7.4 to ver. 8.0.1. That is not a problem since I can choose which version to use... in apache2 config for una site I can use php7.4-fpm and that's it. But cron job for una needs modification
/usr/bin/php -q /path-to/una/periodic/cron.php
/usr/bin/php7.4 -q /path-to/una/periodic/cron.php
or else I get warning to e-mail that "allow_url_include is on ...."
I haven't tried to change the php7.4-fpm to php8.0-fpm to see if it works since the site is live....
