 * Hi there,
    I get a lot of ‘Tag section invalid’ errors in my error log, to the
   tune of hundreds every minute. There’s an example below. What can I do to prevent
   these warnings?
 * Nov 11, 04:43:11 PHP Warning: DOMDocument::loadHTML(): Tag section invalid in
   Entity, line: 476 in /home/cross/www/wp-content/plugins/cache-enabler/inc/cache_enabler_disk.

 * This only happens in combination with the webp option due to not properly validated
   HTML code (verify it here [https://validator.w3.org/](https://validator.w3.org/)).
   However, we improved the warnings handling for invalid HTML. This will be integrated
   in the release 1.0.8. Please reinstall the wordpress cache enabler plugin for
   now.

 * Thx, I’m also in conversation with someone via email. Once 1.08 is on wordpress.
   org I’ll install and let you know.
