I crashed my website trying to secure it by changing files and folders modifications...After i tried many things (chmod 777 -temporarly- all to take it back, clear the cache, drush rr...) nothing worked yet. So i tried to install a new site, copied all the site file...It was working perfectly.
I tried to link the new site with my old database, and the fatal error get back again...I guess my database might be corrupted...Any idea ?
Thanks for your help
