Squirrelmail has gone blank

[dandadude]

Hello!

Today a client has alerted me that after logging in to webmail.domain.tld, they get a blank page. Yesterday all was fine.
Turns out that they had SquirrelMail set to default and SquirrelMail displays a blank page.
Roundcube works fine, alternative solution is to switch everybody to Roundcube, but there are many who rely on SquirrelMail.

I have force upgraded everything, rebooted the server after this and nothing helped. I tried to search logs (but maybe not the ones I need to, so I welcome any ideas) and nothing interesting there.

What is the solution or how can I debug?

Thanks,
Daniel

SquirrelMail was removed in cPanel/WHM version 78

Yeah, but there was a way to get it back I am always up to date and users have been using it successfully until today ;-)

Have you had a look at the main log? (usr/local/cpanel/logs/error_log)?

 

[dandadude]

Yeah, no help from that.
Ah well, did a find/replace on all "/.cpanel/nvdata/[email protected]_default_webmail_app" files looking for sqmail and squirrelmail to roundcube and all is well.
Weren't too many and no other clients complained about this, so case solved
Thanks!
