    Great plugin!!! I started using this plugin recently after an attack and it seems like it’s doing well in finding changed files and etc.

    I started play with Cache function yesterday and on one site, it worked fine but one the other, it gave me error like below…..

    ‘Warning: Cannot modify header information …………….’

    Any idea?
    When I changed to cache option, it did give me a message that it was not able to modify .htaccess file. Does it have anything to do with it?

    Thank you for your help!

    Hello,

    On the first issue, do you have the latest version of PHP installed? Are you running any other plugins and are they up-to-date? Are you running the latest versions of WordPress and Wordfence?

    The second issue is your web server does not have permissions to edit .htaccess. If you can, you’ll need to change the permissions.

    Thanks,
    Brian

    Thank you. I think I figured it out. BPS recommends changing wp-header permission and I believe error message from your cache was pointing to that file.

    Once I make changes and reset whole performace by turning off and on, error message disappears. 🙂
    I’ll report back if it comes back.
