Thank you for your answer.

I solved the problem. It has been a conflict with the Enfold-Theme.
I added some custom CSS to display the datepicker correctly.

I’m sorry for the late response.

Here is the URL of my site:
https://dev.frankenballon.de/
On this site all plugins excluding MEC are deactivated.

This is my live site:
https://frankenballon.de/
Of course all plugins activated and applied the temporary fix for MEC (as desricted in my previous post).

I’ve done these steps to increase Page-Speed:
Caching, Image-Optimisation, CSS and JS compression, clean Database
Of course, some of these are inactive on https://dev.frankenballon.de because plugins are deactivated.

Thanks for your answer!

I did deactivate all plugins except MEC. I measured the page load times of frontend- and backend-pages with GTmetrix and Query-Monitor-Plugins.

The first test is done with the Enfold theme.
After deactivating all plugins except MEC there is no big difference in loading times.

After deactivating MEC the loading time has decreased. Something I noticed in GTmetrix, is that the waiting-time of the GET-Request (TTFB) decreased by three times or more after deactivating MEC.

As mentioned in my beginning post, I think the problem is located in the “import”-function of the “mec-init.php”-file. After setting the “override”-variable to false, I experience similar loading times as with MEC deactivated.

In a second test run, I switched the theme to the default “Wordpress 2019” theme.
With all plugins enabled I measured some slightly lower loading times compared to Enfold themes.
Of course, I measured times with all plugins disabled except MEC. No big differences.
Then I deactivated MEC and the loading times decreased.

I’m using PHP-version 7.2.22 and have PHP-boost enabled.
Even after switching to PHP-version 7.1 or disabling PHP-boost, there is no different in loading time (sometimes even higher than with original configuration).

cURI is enabled on my server.

Have the following Host configurations:
upload_max_filesize = 64M
post_max_size = 76M
memory_limit = 256M
max_execution_time = 120
max_input_vars = 4000
max_input_time = 60

I’d tried to increase max_input_vars and max_input_time to your recommendations, but there are no differences in loading times.

Here are the measurements – if you need them:
