Looking for suggestions on troubleshooting our rt4 instance. We have a CentOS 6.7 VM as our test/dev/machine, running Apache 2.2.15 and perl 5.10.1.
This environment currently has 2 instances of RT running on it, which I can access via the web client, np.
We wish to upgrade to 4.4.1, so I’ve been figuring out how to do that. 4.4.1 has been configured, installed, db upgraded, all painfully but those tasks are complete.
When I direct my browser to the 4.4.1 instance, I get “This page can’t be displayed.”
I’m looking for ideas on what to troubleshoot, things to check.
I’ve checked the Apache error_log and the RT httpd.error log, no real pointers there. I have stopped and started Apache a coupla times, I do get the critical about Mail plugins not being forward compatible. Is that enough to prevent RT from starting?
