also getting the Error: Invalid request headers (err code: 6003)

” cf woker ”

thinking there might be a typo in the code

Someone suggested deleting Super Page Cache and reinstalling making sure Cloudflare Cache Rule in place, which was good suggestion, but it did not resolve issue.

I edited the referenced line of code and that did not resolve the issue either.

I reverted to PHP 8.1,x and that didn’t work.

This is a WP multisite where I had Super Page network and subsite enabled, that didn’t resolve it.

I tried with all other plugins disabled.

Admin Bar shows green, and purge says successful, but Test Cache returns no cache rule message but cache everything rule is in place.

… when saving Super Page Cache settings under any tab, Error: Invalid request headers (err code: 6003) is displayed.

note: other websites with Super Page Cache are working, BUT they also show the error code … in Query Monitor. They previously connected…

WHOA !

Using API KEY… key method, not token…. allowed connection…. there is a green button that appears in Super Page Cache to Continue… this worked and error message does not appear

other previously connected sites used TOKEN I’m pretty sure… they work, but have error message

so can’t mark as resolved as Cloudflare suggests using TOKEN not KEY..

on top of everything else… Super Page Cache is removing the admin tool bar from the front end

Hi @rapidasia,

Thank you for sharing the error and other updates with the community.

I checked and found that the API token method works perfectly on my end. I was able to set up the Cloudflare account using both the token and key methods.

Could you please verify if this issue might be affected by any caching plugins you have installed? Regarding the last issue related to Admin tool bar, could you please share more details about it? Please attach some screenshot as well as that make the debugging process easy for us.

I look forward to your response. Thank you!

Hi, thanks for response.

I’ll try to make sure all other plugins are not messing with the connection.

Cloudflare is the culprit for hiding the admin tool bar on the frontend.

In CF Development Mode, the admin tool bar loads as expected. When using normal cloudflare the admin toolbar is not shown on the frontend, despite being logged in.

Caching rule is “cache everything”

it is nearly impossible to find info on Cloudflare or support for this…

it’s hiding the toolbar with almost all plugins deactivated and the cache purged… go development mode and it displays…

Wondering if you have any suggestions on this… (thanks in advance)

Site is a caching trainwreck for some unknown reason

fortunately new site and I’m going to just punt and create new wordpress install

marking as resolved, simply because impossible to fix

will be sure to connect super page cache with cloudflare before activating other plugins which may have caching
