Invalid markup removed: how to solve this?

It looks like there may be a TagDiv form resulting in the validation errors.

Can you perform a recheck of that specific URL highlight with the form temporarily deactivated?

I’ve temporarily deactivated the tagdiv newsletter plugin and did the re-check but nothing happened.

Thanks for sharing, it looks like you have a number of plugins with validation errors on that particular URL. The plugin has already handled these as you’ll notice by checking the “Invalid markup removed” notice. The URL referenced is also AMP valid.
