[Jetpack and Litespeed] Jetpack and Litespeed conflict – 503 error

Every time I save LiteSpeed changes, no matter whether I change them or not, I´m redirected to this URL https://grumav.com/wp-admin/options.php with a 503 Service Unavailable.

I try uninstalling and reinstalling the plugin but get always the same result. My hosting provider told me to disable modsecurity which I did.

I found that if I disable Jetpack I can save settings and purgue cache without any problem so I guess there´s a conflict between them.

I tried to disable all Jetpack features without disabling the plugin itself but I ended up with the same error.

What can I do about it?
