[Plugin: CKEditor For WordPress] how to stop editor from inserting elements

@mathiasaeschlimann adding <p>&nbsp;</p> in some situations is issue related with CKEditor library. It is known issue. We should wait for CKEDitor developers to fix this issue.

ok, thank you, are there any informations on in what circumstances this gets added or what mark up structures to use for avoiding this?

Wrapping <img> in <figure> seems to prevent <p> </p> immediately after <img>.

This option also can help: link to documentation. I forgot abut it.
