WP Recipe Maker does not allow me to enter text and save it

I am working on a blog post and am trying to enter my ingredients and instructions (etc) details in WP recipe maker but whenever I try to ‘save’ or ‘save and close’, this message appears:

“This is taking a long time. Maybe something went wrong? Click to copy the recipe to your clipboard.”

So I cannot successfully add anything into WP recipe maker, whether that me the name of the recipe or notes, etc. This has been ongoing for several hours now.
