unexpected or invalid content message

I really need some help with this issue. All of my header blocks now have message “This block contains unexpected or invalid content”. They have not been edited or updated since the headers were added.

Hey Robert! We’ve sent you an email. Let’s continue the conversation there ??

Hi,
I’m having the exact same issue.

Once they are “invalid” they are not editable. So I need to make a new block and recreate it all again.

Here are 4 screenshots. After changing nothing, then coming back to the site you’ll see they are “invalid”

If I select a block to try and edit it the right sidebar shows no edit controls

If I click “resolve” this is what appears.

If I then click “convert to block” this is what happens

otherwise, these are nice to work with.
Thanks

I’m also having the issue with containers.

I am having the same issue with the Video Popup as well.

Thanks,

I am also having this issue – every time I create a page and publish it, the block don’t display on the live site. When I go back to edit the page, I’m confronted with the invalid content error.

I am producing a number of websites for my business and have just purchased the premium version of the Stackable theme – any assistance would be great.
