D’oh… that did it! Thanks a lot for the quick help and great plugin! 🙏 I’ve dropped a tip in your Paypal tip jar!
I’m seeing this come up the last few days now as well. Given @djhaystack’s comment and another comment on UpDraftPlus, I think something might have changed with Dropbox.
I’m still getting this error today on version 2.1.2. The code to be replaced in the above solution is any reference to addthis_widget.js, you replace the parameter # with ?.
However, after doing this I just get another set of errors.
Even when manually adding the AddThis buttons to the site without the plug-in, I get these errors.
Any fix for this?
