There's a certain plugin (Aweber slideup) that always keeps working after I deactivate it. Then, it will finally deactivate randomly a few days later, or sometimes not at all.
I'm trying a few different opt-in plugins on my site (bought WPSubscribers but not a fan so far), so it's hard to troubleshoot/test when one plugin stays active all by itself.
I don't want to kill ALL plugins via phpadmin. Is this a caching issue? And if so, why is it limited to just one plugin?
