I have A2Billing set up on a new server, upgrading from v2.0.14 to v2.2.0 but I'm getting the dreaded "Connection failed" white screen of death.
I took the database configuration settings out of /etc/a2billing.conf and was able to successfully connect to our database using the CLI mysql client to connect to our remote server. The old server that we're replacing (and still using) is also able to connect to this same remote server without any issue.
I'm pretty sure that I've got all the file permissions right (going by this thread: viewtopic.php?t=1929
), but I may have gotten something wrong somewhere. I'm definitely not getting any PHP errors in my Apache error log, so that hasn't been much help either.
Any help will be appreciated, and I will happily cooperate with any suggestion.
