There’s a “Javascript broken” error flagged in my ahrefs report this week which seems to relate to Ultimate Blocks. I have two websites and both are affected. See screenshot for example.  

 A couple of pages are affected, here’s one as an example:  

It gives this link as the broken Javascript:  

I don’t know what the scrollby-polyfill is so I can’t look for it to fix. I only really use Ultimate Blocks for the TOC, but one of the apparently affected pages is a tag page with no TOC on it. 

What does this mean and how can I fix it?

This is a known issue that we have fixed already.

The fix will be released with a new version next week.

I will let you know when the update is available.

Kind regards.
