Hi, I’m not going to pretend to know much here, but I think I may be having the same problem. I’m hosted on WPengine and after chatting with their support they seem to think it’s an issue with this plugin, but an easy fix? Anyway, here’s the error:
“[Mon Jul 14 18:29:30 2014] [error] [client 66.249.90.171] PHP Parse error: syntax error, unexpected $end in /nas/wp/www/cluster-1025/jumpstartmd/wp-content/plugins/widget-logic/widget_logic.php(286) : eval()’d code on line 1”
If it’s helpful, the reason I started investigating this was google was denying my Ad requests because it’s bots were getting 500 errors on pages that were (seemingly) loading just fine. Deactivating this plugin has resolved that problem.
Thank you for your help – I hope this is useful
