I can't add posts

For whatever reason, it works!
I will put the site back together.

Thank you for your time!
Great plugin:)
Later edit:
It worked because it was not activated, so the problem is somewhere in the plugin.
Before update, it worked as it should.
I really want to fix it, so if is there anything I can do to make your troubleshoot easier, please let me know.

Best regards,
