Hello Cloudflare Community 
I have a couple of questions. A short one and a detailed one….
How do I eliminate all Cloudflare caching and optimization so that I (or Google) can make a test of my site which totally bypasses Cloudflare? Is it merely enabling development mode? That’s it?
I’m using Google’s Mobile-Friendly Test https://search.google.com/test/mobile-friendly to make sure our websites pass tests and render correctly
I’m seeing intermittent errors on all our sites, but a staging site we have (which is being redesigned with a new theme) seems to be getting the worst results. Here are a couple of sample results:
https://search.google.com/test/mobile-friendly/result?id=630NeO6HYdkwSMP_GR7NKw <<< a straight-out fail – check the tested page > screenshot for awful rendering too
https://search.google.com/test/mobile-friendly/result?id=6mGwRDRv6mohhFnYQzbt5Q <<< page “passes” the test, but the screenshot looks like it hasn’t rendered properly
Of course, the crawl fail error will happen because this one is a staging site, so I ignore that.
We also get a “Page is not mobile friendly” result a lot. Here it is in the LIVE site: https://search.google.com/test/mobile-friendly/result?id=QKTPxFpwG1-hldy6FeDvHA – here you can see the errors: “Clickable elements too close together” and “Text too small to read”. I assume we get this error because of the awful rendered image in the screenshot.
The results are intermittent and sporadic. You could run the tests again straight after and each page would have opposite results. It’s all very random.
Almost every time however, the screenshot section looks awful – no matter what the official result
A “Google Expert” in the Google Community forum said that obviously having the mobile test result show as a fail was an issue, but even if it passes and the screenshot looks poorly rendered – that is an issue too, because this is how Googlebot sees the page.
This happens across our other sites too, but not to the same extent – note though that the screenshot issue is something that is seen across all our sites.
We have run competitor and other website URLs in the tool and most of the time they all pass and the screenshot section looks completely normal. It just seems to be us! Our sites have different themes and setups.
Under instruction of our theme provider (for the staging site above), we have disabled all caching plugins but still the issue persists. Our hosting provider says it is definitely not a server issue. They also suggested contacting Cloudflare support – so here we are – and this is our last resort.
Can anyone help me, it’s driving us mad!
Many thanks in advance
the record should work
