[SOLVED] Error in Login : failed to open stream: Permission denied

Hi, i come back in web site login but when i try to log-on , i have the following error:

file_put_contents(/var/www/vhosts/website.com/httpdocs/application/files/cache/expensive/xxxxxxxxxxxxx/xxxxxxxxxxxxxxx/
xxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxxx/xxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxxx.php):
 failed to open stream: Permission denied

can you help me?

Looks like the permissions are wrong on your cache directory. Can you delete everything in application/files/cache and see if that resolves it?

ok thank you , solved.
