If I click from the homepage to a post, then the main navigation and logo become bigger for a second. What can be the problem?
Customer Support
Hi there,
would you mind flushing and disabling you cache plugin so i can take another look.
So i have changed my site logo and have made some design changes. But the problem is still there.
When I let wp-rocket generate the critical css again, then the problem seems to go for a while. But after some time, it is there again und really anoying.
I have stoped caching with the wp-rocket no chache plugin.
It is possible to exclude some CSS from the Critical CSS. But are you noticing much speed difference without this option activate? Your site is running on HTTP 2 which means optimizing / combining CSS files is not really necessary and actually inadvisable.
Yeah, I have CSS and Javascript Minification disabled, because they recommend it because of http2, as you said.
Butactually I don´t know, if this solves the problem. I will see it tomorrow.
But I also have noticed, that with every refresh of the site, the H1 titles gets bigger for a second.
This is a similar problem. What could that be?

But I also have noticed, that with every refresh of the site, the H1 titles gets bigger for a second.
This sounds like some sort of caching issue. It doesn’t happen on any of my fresh installs.
It doesn’t happen in any of our sites here as well:
https://generatepress.com/site-library/I doesn´t have this problem in the past either. But after I made some changes in customizer, the problem wit the navigation begins. And then the problem with the h1 titles kicks in as well.
Like I said, I have deactivate the Minification, but the problem with titles is still there.
I have noticed, that the problem with the titles are not just h1. Any titles, also in siedebar, have these problems.
With each refresh, the titles gets bigger, like there were bold, and then go back to normal?
What can be the problem? Why do you think, that caching do soemthing?
Sounds like the CSS maybe getting loaded in the footer instead of the header by default.
Can you disable all plugins except GP Premium and link us to the page in question?
I have already linked the page in the initial post. But I can not deactivate all the plugins for long. When is the best time to do this, so you can have a quick look?
We can’t really promise when to have a look.
Maybe it’s best to duplicate the situation on a test server?
As for now, I would assume clear and disabling WP Rocket would solve the issue.
My problem is still there.
But I have this problem only lately. Maybe after updating GP or wp-rockt, I don´t know.
But before, i had not have this problem.
I have wrote to the wp-rockt support and they answered as follow. in particular nr.3 seems to be interessting. How can I do that?
Any other ideas?
What you’re seeing is called a “Flash Of Unstyled Content” (FOUC): https://en.wikipedia.org/wiki/Flash_of_unstyled_content
FOUC issues can be related to our Optimize CSS Delivery option: https://docs.wp-rocket.me/article/108-render-blocking-javascript-and-css-pagespeed#critical-path-css
This option isn’t appropriate for every website, depending on how it’s coded. If disabling this option solves the problem, then your options at that point would be to:
1) Keep the Optimize CSS Delivery turned off for the whole site
2) Turn off the option just for affected pages: https://docs.wp-rocket.me/article/677-turning-off-additional-options-on-specific-page-post
3) Use the Fallback field to specify your own critical path CSS: https://docs.wp-rocket.me/article/108-render-blocking-javascript-and-css-pagespeed#fallback-css
When I inspect your page it looks like you may actually be using a Generate Press option for this as the ID for the critical CSS doesn’t match the ID we would use. The ID for your critical css is generate-style-inline-css whereas we use the ID rocket-critical-css. You could try disabling the option in Generate Press and checking to see if the critical CSS feature in WP Rocket works better for you.
Do you have the CSS options checked in Customizer > General?
If so maybe try unchecking it? That’s the only CSS option from GP.
Do you mean this option?
“Cache dynamisches CSS
Cache CSS, das auf Deinen Optionen basiert, um Deine Performance zu verbessern”It is unchecked. But I don´t know what this mean. What to do?
And it is strange, that I don´t have this problems for years. And suddenly it is there. Can only have something to do with an update.
It was unchecked already?
Nothing in GP’s updates should trigger this.
Might to good to uncheck the Optimize CSS Delivery as WP Rockets suggested or ask them for a bit more info?
