Can't Edit Posts, get server error

[MrFantasy]

I get this error when I try to edit a post by clicking on the edit link.

"The server responded with an error. The error message is in the JavaScript console."

I check the server log and there is no error logged there. I've checked all the user group permissions and everything is ok there (I even get this trying to edit posts as super admin).

Might this have something to do with an addon or something. At a loss on how to fix this.

It sounds like an add-on, possibly one which involves additional JavaScript.

Disable all add-ons and try again.

Awesome, you were right. The XenFacil's Spoiler addon was causing that error. When I disabled that plugin, I'm able to now edit posts and that error message is gone. Thanks again.
