I’m having trouble with the Cloudflare CDN & your plugin. My site is a web shop, so it is a bit more finicky when it comes to caching dynamic content. This is precisely why I wanted to use this plugin.

At the very beginning, I set up the 3 free rules on Cloudflare (bypass wp-admin, bypass ajax, and cache everything), which is when my site had stellar results (I’m talking milliseconds to load the entire page) on Pingdom, PageSpeed Insights, and GTMetrix, and anecdotally the site felt the fastest it had ever been to me then. However, the 3 rules were not enough, as my cart and checkout pages obviously acted up, and that’s a dealbreaker. So, I wanted to buy additional rules, but I came across your free plugin and decided to give it a shot. I deleted the 3 rules, as per a support ticket I found on this forum, and then activated your plugin, as well as the Workers part.

Now when I go to various test speed sites, I get different results. Namely, GTMetrix (whose free server is in Vancouver) still shows the stellar results, but Pingdom is back to being slow (>10s to load the site), and PageSpeed often shows an error accessing the site. I looked a bit further than that and went to Sucuri, which lists various servers, and it only showed the site as accessible via an Atlanta, GA server (that’s likely where my origin server is btw, I’m on DreamHost). As for other servers, it reads: Could not test website from this server. Additionally, it feels slow again for me. This tells me that the USA server is the fastest because the origin server is located there, and the CDN is not working properly across the globe.

The Cloudflare analytics show that Workers are working and that data is being sent through them. But I’m not seeing any results. Please advise? Thank you in advance!

I’m enjoying using the W3 Total cache plugin. I have put a form using contact form 7 on the website and all is fine except the speed when I click submit and it takes about 7 seconds to process and redirect to Thank you page.

Is there something connected to this plugin I can do such as combining JS and CSS as my Pingdom Tools score shows an F for ‘make fewer HTTP requests’. Hope you can point me in the right direction.

I turned off ‘Lazy Load’ in LightSpeed Cache. I also turned off all settings but images still don’t show as long as the plugin is activated.

Same problem on all my websites, hosted on same server.

Thank you

So, I looked at what is slowing the site down. https://prnt.sc/wnhizv

I deactivated the language detector which improves a bit because I had more than two seconds of difference. But still, I would like to improve a little further. Do you have any suggestions please?

Thank you in advance and my post is not meant to be a negative review of your plugin which does a wonderful job.

As with all other WordPress related issues, I always find out, that I’m not the first one experiencing this

So that’s why I reach out to the WP Forum; How have you solved for these suggestions on your sites? Are there any “quick fixes” or do we all need developer help to around this?

Pingdom tools suggestions:

F0 Make fewer HTTP requests
F0 Add Expires headers
F5 Reduce DNS lookups
F12 Compress components with gzip
F30 Avoid URL redirects
F30 Use cookie-free domains

There is an error appearing on GTmetrix and Pingdom about Onesignal.

Leverage browser caching for the following cacheable resources:

Here is the screenshot: https://prnt.sc/pa9e1p and the page in question is https://nakib4tech.com/

How can we avoid this issue, please?

When I disabled this plugin everything works fine.
As I have removed the plugin, I cannot point to any reference url.

Can you please help me using this plugin??

Rejected User Agents

Strings in the HTTP ’User Agent’ header that prevent WP-Cache from caching bot, spiders, and crawlers’ requests. Note that super cached files are still sent to these agents if they already exists.

bot
ia_archive
slurp
crawl
spider
Yandex

I was testing caching using https://tools.pingdom.com/ and it was showing high page load times when caching was enabled. This was confusing because curl was pulling down the super-cached file fast. When I tested using curl with the a bot’s user agent, as shown below, the response was slow.

time (curl -A "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/61.0.3163.100 Chrome/61.0.3163.100 Safari/537.36 PingdomPageSpeed/1.0 (pingbot/2.0; +https://www.pingdom.com/)" https://www.morningstarsecurity.com/news | tail)

Removing the Rejected User Agents list resolved this problem. Testing with Pingdom showed that the page loaded fast. This is a bug in WP Super Cache and the workaround I used works fine.
