I’m using Ubuntu 16.04 and recently upgraded the server to php7.3 from php7.0 but then was unable to open any libretime pages (Ooops something went wrong).
I note on github that php7.2/7.3 support is quoted on ubuntu 18.04, is there an issue running php7.3 on 16.04? Do I need to re-run the installer or should it ‘just work’ ? Thanks.
Can someone please help me debug this a bit further? Under php 7.3, all the airtime services are running but the webpages can’t be generated;

no errors are generated in the apache2 error.log, at rest or at login. Downgrading from php7.3 to 7.0 and airtime works again, no services needed restarting 
Please let me know what other logs you want to see…
Re-running the installer with php7.3 enabled doesn’t seem to make a difference to the installer… it’s checking for php7.0 files…
php7.0 is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).
php7.0-curl is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).
php7.0-gd is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).
php7.0-pgsql is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).

OK, simple environment error… zendphp.log > Unable to open PDO connection [wrapped: could not find driver]
Comparing info.php for both versions, in php7.0 I have;
PDO drivers|mysql, pgsql
in php7.3 I have;
PDO drivers|mysql
Installing the missing pgsql driver
sudo apt install php7.3-pgsql
fixed it up and everything worked immediately. I hope this helps someone else
