Hi @deontdekkers

I hope you’re well today!

Please first check if you can successfully test the site with Google’s PageSpeed tool.

If it doesn’t return any results (returns an error), this would most likely be more general issue – maybe related to the site being overloaded or “way to slow” or due to some sort of security settings (e.g. country blocking).

If it does return results (regardless of the score), start with making sure that your site – security plugins – and your host are not blocking out IPs in any way. Making sure of that is the first and fundamental step.

You can find those IPs here:

https://wpmudev.com/docs/getting-started/wpmu-dev-ip-addresses/

If that’s not the case or it doesn’t help, update us and we’ll see what to do next.

Kind regards,
Adam

I check Hummingbird on a clean installation to see if the host is blocking anything. But it is working fine on a clean install.
I have made the IP’s trusted IP’s in my security plugin, without succes. As a last resort I deactivated every plugin but Hummingbird, but still the Performance report won’t load.
Next I tried removing Hummingbird with the Delete data and Settings option, to have a clean install. Wizard of setting up optimizations worked, but the performance test still didn’t.

Weird thing is Google’s Site Kit is also giving an error on the performance test. But when I open PageSpeed Insights I do get a result: https://pagespeed.web.dev/analysis/https-www-de-ontdekkers-nl/s11gywyo4c?form_factor=mobile

Hi @deontdekkers,

Could we know whether you checked if there are any improvements with the performance scan after clearing the cache in both the plugin and in the Hosting side?

Would also recommend checking whether there are enough server resources too.

Having a memory_limit of 512M and max_exeucution_time of 300 would be ideal.

You can check this article on how to increase the resources.

https://wpmudev.com/blog/increase-memory-limit/

If the issue is still the same even after increasing the resources, then please do check how it behaves if you temporarily disable all the plugins except Hummingbird to see how it behaves?

The above test would help in giving a better idea if there are any conflicts. If possible, better to check how it behaves with the Site Kit plugin disabled too.

Please do check and let us know how the above goes. Looking forward to your response.

Best Regards,

Nithin

Memory use is only at 26 of 512M. Changed the Max_execution to 300.
Allready tried Hummingbird as the solo plugin installed, but dit it again with the same result. SiteKit works only after a retry, but fails on every first attempt.

Strange thing is. The loader seems to do fine, it says the test ran succesfully. Only the displaying of the test results gives an error.

Hi @deontdekkers,

Hope this message finds you well.

Could you try this mu-plugin? https://gist.github.com/wpmudev-sls/a1ae481c433606a4bc3f53edb5bb7c27
Some sites have been experiencing this issue when Hummingbird Assets Optimization + Site Kit by Google is used, our Second Line support did create that as a workaround.

Please extract it and upload the hummingbird-google-kit-fix.php file to your wp-content/mu-plugins folder. If that folder doesn’t exist, you can simply create it (the whole process is described in this help article).

Also, you might need to exclude this file from

Hummingbird >> Asset Optimization

Let us know the results.

I’ve done as you said. But still: There was a problem fetching the desktop test results. Please try running a new scan.

Hi @deontdekkers

Thank you for update!

After reading this all topic again, there are two things that got my attention additionally:

1. it seems this is only happening on this specific website – as you tested on other and it worked there

2. and, more importantly, SiteKit also seems to be suffering from the same issue.

That strongly points to something very specific to that site but I’m just not sure yet what that is.

Could you please check something more then?

1. Is your site behind CloudFlare? if yes, could you temporarily pause it and see if that changes anything?

2. Is there any server-level caching, especially object cache (but any other type as well) and if yes – is it possible to temporarily disable it to see what happens without it?

3. and if none of that helps/is related, could you please try running Performance Test again (in both plugins separately) but at the same type keeping browser’s dev tools (preferably in Chrome browser) open and checking “Console” and “Network” sections of them?

If there are any errors reported in Console or there let us know about them (include errors) and if in Network tab there are also failed requests (especially admin-ajax requests) let us know what are they and what is HTTP response status for them reported.

Here is more about using Chrome dev tools:

Best regards,

I disconnected any server caching but the problem was still there.

However I got it working again. After reinstalling my current version of WordPress the problem was fixed (and I reconfigured SiteKit, but I don’t think that will be related).

Hello @deontdekkers,

Hi @deontdekkers,

Since we haven’t heard from you for a while. I’ll mark this thread as resolved for now. Please feel free to open a new thread if you have new queries.

Hi. Yes sorry been busy and forgot to reply.
A little update: The problem returned and the origin was finally traced to the Redis object cache. I thought it was disabled but in the background it was still active for some reason. After disabling it worked like a charm (and a lot of other things with it).
