Whith the "SQL injection attacks" protection enable I got "Forbidden You don’t have permission to access.. " but only if the Folder name, inside Owncloud, contains the "º" character.

Anything I can do besides turn off SQL injection attack protection for that particular Web site?

 

Thank you

  • Hi Joao,

    Instead of disabling the filter for SQL injection, simply add the "id" that you can see inside the log lines in Skip Filter Rules option you can find within the Firewall Profile you use for protecting the virtual server definition.
