Generator tab access denied in 1.4.3

[AuroKT]

Hello!

After a upgrade from 1.4.1 to 1.4.3, the Generator Tab is not working, with a access denied error.

I see that others that had this problem solved with a new install, but I really don't want to risk new problems or data loss in the process.

Can someone tell me what to change in the htaccess file, so the new pictures show like the old ones?

If you know what is causing the access denied problem, a little help, please?

Thanks for your time.
