Didn't see this in the RCs, but I installed 1.8 and now I get 500 error when I try to reach config. All other CB links work fine. Nothing found in error log. I'm on php 5.3.10
this issue is keeping my moderator approval emails form going out it appears I just didn't have an email in that spot stupidly
I also get this error when I click on System Info it that helps
switching back to 5.2.17 fixes this issue, talking to my host now
CB 2.3, CBsubs 4.3, PHP 7.1, J! 3.9.X
