Formatting doesent get saved

Hi there,

we have a customer using this cool plugin. Its time for some updates in the content but we are not able to save content with html like <h3>title</h3> anymore.

In the past it works without problems and i don’t know when it was updated last time… but now the formatting disappears if you click save.

I made an video to show:

I already used Health & Troubleshooting Mode and test it with all other plugins deactivated … doesent help.

Can you help us?

Greetings
Henry
