OpenLiteSpeed + WordPress + WP-Rocket Cache plugin

Hi,
WP-Rocket page cache plugin for wordpress adding some code to .htaccess
As a result, when accessing the website with OpenLiteSpeed we getting download file instead of open the website

Anyone else bump into it? Ideas?
I don't see the the problematic location in error log

Regards,

OpenLiteSpeed loads .htaccess on starting time and it only supports RewriteRules there. I'd suggest using LSCache plugin, which is the best option with LiteSpeed/OpenLiteSpeed, as it's caching directly to the webserver
