[Plugin: Print Friendly and PDF Button] 'Something Went Wrong' Error when selecting PDF op

Thank you for the great plugin!

I receive the “We’re sorry, but something went wrong” message when I click the PDF button. For testing purposes, you can try it here:

Additionally, the pop in ads cover the error message when this happens, with no way to close them. Is there a premium version of this plugin that does not use ads?

Thanks!
