• Installed WP Super Cache today and everything seems to work beautifully except the Home page does not seem to be caching at all. The comment code at the foot of the HTML source appears on every page except Home. When I try running a Cache Tester (from the Easy tab) I get the message “The pages do not match! Timestamps differ or were not found!” – in my case, it’s because there are no time stamps on the Home page. Timestamps appear on all other pages.

    Another thread recommended disabling the “Cache rebuild” option, but that didn’t help. I think that is to solve the problem of timestamps not matching.

    Any suggestions?

    Further to my earlier post, I have found these lines when debugging WordPress:

    [28-Sep-2016 17:30:02 UTC] PHP Notice: Undefined index: HTTP_HOST in /home/xxxxx/public_html/wp-content/plugins/wp-super-cache/wp-cache-base.php on line 4

    These errors may be related to the problem. Anyone know?

    No progress yet unfortunately.
