Hi Nicolas,

You can see my Settings below…

You wanted some pics…
Settings: https://prnt.sc/s6tpeo
Customizer: light grey empty rigt side with and without activated Plugins
https://prnt.sc/s6syvp

White Startpage (all Plugins akctive AND all Plugins deativated)

When I deactitivatet all Plugins at once I got:
WP-Filebase API request error:WP_Error Object ( [errors] => Array ( [http_request_failed] => Array ( [0] => cURL error 28: Connection timed out after 5001 milliseconds ) ) [error_data] => Array ( ) ) Warning: Cannot modify header information – headers already sent by (output started at /customers/c/9/6/stadtteilbuero-ohligs.de/httpd.www/wp-content/plugins/wp-filebase/classes/ExtensionLib.php:37) in /customers/c/9/6/stadtteilbuero-ohligs.de/httpd.www/wp-includes/pluggable.php on line 1281 Warning: Cannot modify header information – headers already sent by (output started at /customers/c/9/6/stadtteilbuero-ohligs.de/httpd.www/wp-content/plugins/wp-filebase/classes/ExtensionLib.php:37) in /customers/c/9/6/stadtteilbuero-ohligs.de/httpd.www/wp-includes/pluggable.php on line 1284

A friend copied the site to another server, there it works… He cannot say why, maybe ist is because his php is a bit older?
Looks like: https://prnt.sc/s6tqtt

My Privider one.com says, they cannot find any problems in their system, I should contact the theme-maker…

Hope, you can help me

Looking at your error message, there seem to be an issue with the plugin “WP-Filebase”
Your server config ( PHP version, and other settings) looks good. And I’m not able to reproduce this problem on my tests when using a similar config. The theme works fine.

The really weird thing is that you have a blank page even when all plugins are deactivated.
TRy to switch to a default theme like Twenty Twenty to see if it helps.
Other than that, I don’t have any other ideas for your problem.

Thanks for your quick response…
Everythink works with another theme (2016 for exampe) also the startpage ..

But the site works good with your thme for a long time…
Hoped, I don`t need to design it new with another time…

And the startsite works on another server.. ?? Don`t wat to change the provider…
