Hi WPMU Support,
On Friday afternoon we found ourselves unable to to log into any of our websites. We contacted our hosting support and they discovered the problem was WP defender on ***life.com had generated a ~200GB error log file.
The issue only occured on the production side, not staging if that helps you figure out what is going on.
We’ve deactivated Defender on the site and even though I’m not holding my breath for answers any info on what might have caused this could be really useful.
