I have a PHPBB Forum version 3.0.8. Today I tried to create a new forum with the first post being my own including an uploaded attachment .docx file. I just wanted the users on my forum to be able to see my post and click the attachment so they could view the word document. The forum however said that file format wasn't allowed to be uploaded. Is there any way to tweak that setting in the Administrator panel to allow word documents and possibly .pdf files to be attached in posts?
