[SOLVED] Roundcube stops working

Evening
I have a strange issue and I have try all options that I have on my mind, but nothing works. I have a multiserver installation of ISPConfig 3 + roudcube from this guide https://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2
Everything works fine, till last week when after login to webmail, each time I got ERROR 500. I may have a clue why it's stop workimg. Last week I have try to enable HTTP/2 protocome by enabling mod_http2 and mpm_worker or mpm_event. Therefor I have to disable mod_php. However each time that I have try to do that, everything stops working. sites or ispconfig. So after many tries, I just give up. I have rollback changes, but realize that webmail is not working now.
The symptoms are. Login page is displayed but after trying to login, got error 500

So my understand is, that for some reason when Roundcube is served apache is using php-fpm instead of mod_php. However I don't know why and I have no idea what I'm doing wrong.

Any clue where should I check else? I would be grateful for any advice.

Thank you

 

There are several threads in this forum about this issue (global site for all webs with php_fpm, also affects phpmyadmin).
Long story short: Install roundcube in a dedicated (sub)domain (there are other solutions, you will find them)

See: https://www.howtoforge.com/communit...be-enigma-munin-phpmyadmin-aliases-fix.77489/

 

Yes I did, I have enable php7.3-fpm for sure. But after this change, php fpm crushes. I will need do analyze that latter.

Thank you Steini86, I will fallow up this thred

 

Ok I have manage to resolve the issue. I have fallow up this instructions
https://www.howtoforge.com/communit...be-enigma-munin-phpmyadmin-aliases-fix.77489/
But this doesn't work. Still got 500 error after login. But I noticed one thing in error log

Code:

PHP Fatal error:  Class 'Net_IDNA2' not found in /usr/share/roundcube/program/lib/Roundcube/bootstrap.php on line 405

Apparently php-net-idna2 package was missed from my system. For some reason. Installing it, solves the problem.
