Our product page has crashed

This is what it should look like (used to look like before): https://www.kindby.com/wp-content/uploads/2021/03/Workingversion.png

I used WP Rollback to install previous versions of the plugin, and that still doesn’t work, but when I deactivate the plugin, the problem goes away (though of course the content I need is not shown)

The error seems to be here as per the error log:
//Parsing custom parameters string
if ( isset( $params ) ) {
parse_str( $params );
}

That code sample doesn’t exist in this plugin. Maybe post the full error message?

Looks closer to this honestly, which is a completely different plugin:
https://github.com/kkemenczy/openscope/blob/master/wp-content/plugins/improved-include-page/iinclude_page.php#L111-L112

Yea, we tried using that after this one crashed – it ended up being the exact same problem actually. So, i may have pasted in the error code afterwards.
