SG Optimizer incompatibility with Advanced Views Framework: Lite Edition

Hello there,

When Advanced Views Framework: Lite Edition plugin is active, and I navigate to Speed Optimizer > Frontend, displays error “COULD NOT CONNECT TO THE WORDPRESS REST API”.

The only security plugin active is SG Security Optimizer.

.htaccess content follows:

# SGS XMLRPC Disable Service
<Files xmlrpc.php>
	order deny,allow
	deny from all
</Files>
# SGS XMLRPC Disable Service END
# HTTPS forced by SG-Optimizer
<IfModule mod_rewrite.c>
    RewriteEngine On
    
    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END HTTPS


# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

# SGO Unset Vary
  Header unset Vary
# SGO Unset Vary END

Is there a solution for this issue?

Thank you in advance,
AP
