I just signed up for the free trial and the first thing I attempted to do was install Smush Pro. As soon as I did my site crashed (see attached). I contacted my host who determined that Smush (regular, not pro) was causing a fatal error. I didn't deactivate Smush prior to activating Smush Pro, but I think it caused a conflict, which caused the site to crash. I just wanted to let you guys know there may be an issue with this. Thanks.
