Causing publishing failed error

Hi

I’m using your plugin on my portfolio site to add references to related evidence posts (at the bottom of completed pages). I purchased the pro version to access the filtering options, which work well.

I’m overall very happy with it, except the lack of ability to save default colours etc.

It’s actually working fine, but when I add a post block to a page, I get an error: Publishing failed. The response is not a valid JSON response.

Most times, the publish has actually worked despite the error, but it’s not making for a smooth workflow.

If I remove the block, the error goes away.

Many thanks
Nicola
