Yesterday our site began returning server errors and couldn't get into admin. I moved all the plugins to a renamed folder and the site came back up.
After reinstalling each in sequence, widget-logic is the one that causes the failure.
We use widget logic quite a bit and it has worked fine. Yesterday, before the crash, one of our members was adding a sidebar widget with logic, after which we experienced the crash.
I queried the wp_options with the key 'widget_logic' and parsed out in excel all the s: elements which number about 180. Is there some limit after which we hit a ceiling? Or is there perhaps some corruption in the record? Are there other records I should look at in the database?
