Forbidden error on clicking "Next: Add data"

[Hafeez Oluwajuwon Adepoju]

Greetings!

I get a forbidden error on CKAN 2.7 after filling the add dataset form and clicking "Next: Add data". This happens when textarea fields are filled beyond 1 row and some field do not also take values that contain urls. For instance, entering a reference to web resource such as DOI.

Please, is there anyone who has witnessed and solved this.

Thanks.
