Recently, I disabled Efficient Related Posts on my primary site, http://www.technightowl.com, for testing. Now, when I try to activate the plugin again, I get that Internal Server 500 error after a few minutes. I made sure there were no other installed products that competed. For now I’m using someone else’s related posts plugin, but I’d rather use yours.
Have the same problem. I assume there are too many queries created by the plugin and it cannot load them when activating.
Can someone let us know where is the plugin writing in the DB, because I couldn’t find that. Had to disable it when testing the fcgi and now doesn’t want to start nor with suphp nor with fcgi. Tried to complete remove the plugin and reinstall – the same thing happens…just times out after like 5min and I have my php timeouts set at 1200 sec.
Otherwise the plugin works very nice until deactivated.
