I’m going to mark this as resolved unless there are any other issues.
I did just make some minor updates – so, try re-installing the plugin and see if it works. If not, I would imagine that it is a conflict with your theme.
We have tested Verbatim with numerous themes without conflict.
I don’t see that the verbatim javascript is even being loaded, though I do see an error in your theme’s js file, so it might be an issue with the theme you are using.
Can you check to make sure the plugin is activated?
Can you link me to the wordpress site you are trying to use it on?
