Compatibility Issue

This error message appears in plugin page.

Hi @gidomanders,

Thanks for your reply.

I had setup W3TC following indication of Cloudways KB:

https://support.cloudways.com/wordpress-w3-total-cache-configuration-for-optimal-performance/

And also for themes related matters, I used the settings recommended by theme developer:

https://docs.presscustomizr.com/article/243-speed-up-the-hueman-theme-how-to-setup-w3-total-cache-plugin

Is there something else to setup? What could be wrong?

Thanks for your time.

Hi @gidomanders,

Thanks for your reply.
Yesterday I upgrade to PHP 7.2. I looked in the error log file from today and yesterday. It does not seem to have anything to do with the W3TC error.

I only find this error display indefinitely, where only changes the referrer:
example:

I checked what theme.php in line 136

/**
 * Whether a child theme is in use.
 *
 * @since 3.0.0
 *
 * @return bool true if a child theme is in use, false otherwise.
 **/
function is_child_theme() {
	return ( TEMPLATEPATH !== STYLESHEETPATH );
}
