Add on page empty after upgrading

[elwe]

I upgraded my site from 1.6 to 1.7.1
Now my add on page is empty.
I read in this forum to add &errors after the admin addon URL.
I did it but I get no error description.
SOmeone has an idea?
Thx in advance for help

yeah, well searching the forum a bit more would help.

I suggest you delete the _defensio folder by using the FTP and see if that solves the problem.

Please post back if that solved it or not.

Blame on me...
That helped!
I promise to search the forum better next time ...
Thanks!
