I am not sure how but I got this error for a long time... seems like no one has same issue as me so I decide to post here...

FuBar2 is working great for me, most older plugins work fine with FuBar-compat-1.2
One issue I'm having is that plugins aren't saving their location properly. I'll move around things, ReloadUI or Logout, and the plugins are in random places. I've seen this mostly with some of the newer Plugins, like MailFu and FactionsFu
I have same problem with Squishy and BugSack plugins... I have to adjust them everytime I log in my character.
