It appears you’ve done something to your theme:
Parse error: syntax error, unexpected '=' in /home/nomadbro/www/gregslens/wp-content/themes/rhythm/functions.php on line 4
When you’ve fixed that file, we can work on the rest.
Fixed it – adjusted the function.php to:
//* Remove query strings from scripts
function _remove_script_version( $src ){
$parts = explode( '?=', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
You still have the same error in functions.php.
I think it’s your cache.. Just checked on 3 different devices.
I just tried in an incognito window and a different browser. Before you remove query strings, it might be a good idea to understand why they’re there. Please comment out that code so I can see what you’re talking about. (Note: I have to go out for several hours and my not be able to respond for a while.)
removed it – function.php is in it’s original form again
Hmmm.. I still get the same error. I wonder if W3 Total Cache is messing things up.

Okey I deactivated it and installed WP Fastest Cache instead. The backend is already way faster, but I still struggle with the query string issue and loading time..
Some of the slow content is due to mixed content. Install the plugin “better search replace”. Search for http://gregslens.ch and replace with https://gregslens.ch.
