I am getting the following warning on WP-Foro.
SPAM! - Possibly spam file attachments detected by wpForo Spam Check. Please check for suspicious files in the forum > Tools > Antispam Tab.
Under this tab, there is a file named ".class-wp-cache.php". Even though I delete the file both via FTP and via the plugin, it comes back and I keep getting warnings.
How can I delete this file?
The sample data content in the relevant file is as follows. Frankly, I don't know what kind of damage it does.
