Plugin killed the website

Hi,

Installed plugin and, upon activation, site is dead.
Here is PHP trace:
#0 /home/cupids/cupids-wp/wp-includes/class-wp-hook.php(287): pvtfw_variant_table_scripts(”)
#1 /home/cupids/cupids-wp/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array)

First problem — I do not have WooCommerce running yet and seems that plugin does not check dependency on Woo.

Now, for interesting part!
I de-activated plugin and… problem is still there. Same error. SO, de-activation obviously not working.
I then tried to delete the plugin and got the message “Can’t delete while plugin is active on main site”. Mind you, plugin was de-activated at this stage. I have screenshot of de-activated plugin that is, in fact, active!
So, I had no choice, but to delete the plugin from Linux command line to get my site back.
