it causes problems in config.php

Hi,

The W3TC is adding/removing one line that is telling WP that there is a cache enabled/disabled.

Check you permissions to the config file.

google also messaged me that your websites is compromised and may be hacked
i downloaded the site data and check it with anti virus but nothing malware there , my hosting company also checked it but they said there is no malware
please help

Hi,

You can check permissions of the file/folder via FTP client or if you have cPanel via File Manager.

About malware – this could be JavaScript embedded in some of your files/database. Good lead is if there is a PHP base64_encode function added somewhere in your files/database. If this is not up to you to check, find some guy/gal that is more involved in programming/WP to do the check for you.

Just for precaution – change all your passwords for your site.

Regards,
