Also when I select the option Compress pages so they’re served more quickly to visitors. (Recommended), by updating, I get the message: ?Zlib output compression enabled!

PHP compresses the data that is sent to your site visitors. It is recommended that you disable this, as the plugin caches the compressed output only once, rather than compressing the same page over and over again. See also section 21 in the Troubleshooting section. See this page for instructions on how to modify your php.ini.

I have a problem with the plugin configuration, I have enabled some configurations, but, when I test cache, I get the message.

Can anyone tell me what could be happening? Thank you,

Julia

(I haven′t updated plugins or WP to v.5.5)

The pages do not match! Timestamps differ or were not found!

“2. Enable logging on the Debug page here. That should help you track down the problem.
3. You should check Page 1 and Page 2 above for errors. Your local server configuration may not allow your website to access itself.”

You lost me there. I understand that the last tab is for debugging but I don’t know how to use that tab or what to do with the information provided.

Thanks in advance.

My cache testing was noting that the “Timestamps differ or were not found,” but the debug log was clean. Everything was loading as expected, and caching was performing beautifully.

After spending quite a bit of time trawling through every possible variable that could have been affecting this, and reading through numerous support threads of people experiencing similar issues, I found the issue.

If you disable “Cache Status Messages” in the debug menu, the cache timestamps cannot be tested.

I’d recommend either noting to the user that Cache Status Messages must be turned on for testing to work, or explicitly bypassing the setting for Cache test pages (the better option IMO).

Finally, any kind of code minification that strips out HTML comments also breaks the cache tester.

I experienced this with Cloudflare’s CDN-side HTML minification, and with the WP plugin Autoptimize. This is no fault of the plugin, and getting past it would require a complete re-think of how to test cache timestamps. I’d recommend displaying a message to the user to disable minifying features when the “Timestamps differ” message is shown.

The Error are occurring then testing cache with Cache Tester under Super Cache option: “Fatal error: Cannot use object of type WP_Error as array in /home/username/public_html/wp-content/plugins/wp-super-cache/wp-cache.php on line 977”

Also “304 Not Modified browser caching” missing under “advenced” options.

Any ideas on how to fix these issues?

When I click on the “cache tester”, the following results gained:

The pages do not match! Timestamps differ or were not found!

I wonder why the screen reveals “The pages do not match! Timestamps differ or were not found!”. Is anything wrong? I want to get it clear immediately. Please help me. I have a bad headache for more than 10 days over this issue. I need your great help.
