Hello,
This issue is related to your server settings, as all existing elements load on the backend when loading the page.
Since our theme includes a large number of elements, this situation occurs. This issue will also arise with a default theme if you add more than 30 third-party elements.
To resolve this issue, please add the following code to your site’s .htaccess file.
<IfModule mod_substitute.c>
SubstituteMaxLineLength 10M
</IfModule>
Best Regards,
