Meta Box

It is now displaying again in the way it should (I disabled WP debug), but I am unable to make any changes to a form, as they are not being saved. I receive the message ‘Invalid request. Please try again.’

This issue persists. New website and AGAIN this issue. Post type doesn't solve it. @Fransesco you mentioned in your last answer the ID of the editing page. Where can I find that and correct that?

I've checked it with Bricks support. This was there answer:

"First of all, I am not very sure why the Meta Box team suggested you to reach us. This doesn't makes sense as the Submission Form element was created by them, totally zero code maintained by Bricks. We got no idea how their form works.

I just checked and compared your form setting in the page, seems like you just need to indicate the object type and it's working fine."

So I checked the object type to 'post' and it is working fine now.

Any chance of an answer within the next 24 hours? As I have to go on with this website and now am stuck with this. Thank you in advance.

Thanks, that is what i meant and solved now for me.
