Blank addons page

Hello I’ve tried to import a addon from file and now my addons are blank.
I’ve tried to reinstall on my mac and still a no go, I get this error in the info when I try to open the addons.

Traceback (most recent call last):

Also reseting factory doesn’t work.

Please help

What addon were you trying to install? Have you tried removing the addon manually from the addons folder?(not quite sure where it is on mac)

Any of them, I was following a scripting tutorial and after running the script it knocked out my addons.
I found out its a bug in 2.78 and I had to reinstall the program

I have the same issue, however reinstalling does not help. Any ideas?

You have to wipe out all of blenders folders before reinstalling
