 * Hello [@keepsmilyn](https://wordpress.org/support/users/keepsmilyn/)
 * I am sorry about the issue you are experiencing and I am happy to help!
    This
   means that you have invalid regexp when excluding a page from being cached in
   Peformance>Page Cache>”Never cache the following pages” Also check if you entered
   the same page twice. Please check the [FAQ](https://github.com/W3EDGE/w3-total-cache/wiki/FAQ:-Usage#which-textareas-for-file-entries-support-regular-expressions)
   page for detailed instructions and this [article](https://www.dropbox.com/s/kv1qi3rzi13wef7/How%20to%20exclude%20page_pages%20from%20cache_.docx?dl=0)
   may help you also. Thank you!

 * “Never cache the following pages” option under Performance > Page Cache is empty
   on our website.
 * We do have entries in “Cache exception list:” however. Maybe thats conflicting
   also.
 * I remember having entries in there for our woocommerce store so have put them
   back (as they are critical for our site). So now it includes the following only:
 * shop*
    cart checkout wp-.*\.php index\.php /?fl_builder
