Copy and paste the entire HPF alert in your forum reply. I assume what is being detected by HPF is a default server php error log file in your /plugins/ folder.
That is all that is in the error log in the plugins folder

Ok so if this is a default server php error log then the name of the file would be: error_log. If this is not a default server php error log then use the filename whitelist rule displayed in the HPF alert or just delete the php error log file in your /plugins/ folder. You should not have a php error log file in your /plugins/ folder.
