When I activated the plug-in, it caused a 'critical error' notification and locked me out of my site. It was necessary for me to deactivate all plug-ins via php-Admin.

I just made a second attempt and the exact same thing happened. I called BlueHost and they stated a strong probability of your plug-in being incompatible.

I used the following Themes: Divi, Elementor (Pro), Envato Elements and Hello with Elementor.

The reason I'm giving you a 3 as opposed to 1 is that the plug-in seems to be absolutely amazing and I'm bummed that I can't use it so I don't want to condemn your talent. But as a one-man shop with over 10 websites, I'm not in the position for a site to crash so I'm just going to stick with the tride and true plug-ins via wordpress.org - some stuff - I'd rather pay monthly than to risk things ike this happening again.
