after installing nivoslider and preparing the slides within the nivoslider modul, the modul didnt saved the uploaded slides.
I tried to re-login and the entire admin panel (simple theme) didnt worked anymore and the screen remained completly blank and returned back to the login form.
I also tried to deinstall the entire modul folder and refresh with /dev/build?flush=all
any ideas what db and config entries I have to delete in order to restore the sites without the nivoslider modul?
thanks for any advice
