Hi,
My site is WP 6.2, PHP 8.2, W3TC Pro, using memcached, Genesis framework with W3TC extension installed, Fragment cache extension.
Performance –> Fragment Cache option is gray but clickable. When I go to Fragment Cache I get a WP fatal error. Enabled WP debugging but no debug log is created.
Thank you for reaching out and I am happy to assist you with this.
Can you please confirm that the Fragment Cache extension is enabled in W3 Total Cache Performance>Extensions, also, In Performance>General settings, please make sure that you have selected the Fragment cache machining method and saved all settings.
Thanks!
