Hello Eli. I use this plugin on a number of wordpress sites. During the monthly site maintenance, I noticed the plugin got deactivated. Seems to have occured only on Bluehost sites. Not sure if Bluehost did it, or some other entity. Just letting you know in case this is a happening elsewhere.
Here is more information. There was a malware situation that changed the injected an htaccess file in /wp-admin causing 403 error to all admin pages. In the process, GOTMLS was DEACTIVATED. Fix was to replace the htaccess file and activate GOTMLS.
