Cloudflare and "Popup Maker" Wordpress Plug In


I use the wordpress plug-in “Popup Maker” on my site ( but have noticed that I receive an error notification from the plug-in that reads as follows:

“Popup Maker detected an issue with your file system’s ability and is unable to create & save cached assets for your popup styling and settings. This may lead to suboptimal performance. Please check your filesystem and contact your hosting provide to ensure Popup Maker can create and write to cache files.”

I’m assuming this is an issue due to Cloudflare’s caching. Does anyone have any experience with this and know how to solve the issue?

I’ve had a look in the plug-ins error log and this is the error recorded:

2023-2-06 13:41:56 - Cannot access cache file when tested. Tested file: Error given: cURL error 28: Operation timed out after 5001 milliseconds with 0 bytes received

Thanks in advance,



I was able to access the JS file without issue, both in a browser and with cURL. In both cases, I made two requests, the first one got a MISS from Cloudflare cache, the second one a HIT.

The issue seems to be a timeout, rather than a block. What made you initially think it was related to Cloudflare? Perhaps your origin server will occasionally take a longer time to respond, resulting in this error?

Hi cbrandt,

Thanks for the reply. I assumed it was a Cloudflare issue as the error has only been present after moving to Cloudflare, but it seems that may not be the case.

Would you suggest that there isn’t really a problem here or should I look for a new pop-up plug in?
