File Upload issue: Forbidden. You don't have permission to access this resource.

Hi Zaba, 

Is there anything listed under: Admin > General > Server Info that says "Security Modules". 

Usually, this is caused by a web server security module such as ModSecurity or Suhosin blocking access when it detects certain types of URLs.

If that is the case, you can email your web host and ask them if they can disable that feature for the /cmsb/ folder as it's preventing you from uploading files.

Otherwise, feel free to submit a second level support request here with a link to this post and steps to reproduce the issue:

Thanks!

Yea, Mod_Security could be the issue.  See if your host can disable it for the cms folder.

The server people say there is nothing in the log files

Dave has sorted this. It was an issue with the upgrade of the uploads table.

• I re-uploaded this file from the latest CMSB release: /public_html/cmsb/data/schema/uploads.ini.php
• I clicked on: CMS Setup > Section Editors.  This automatically checks all the schemas and adds missing fields (it added some columns)

I thought i'd add in here as a port of call for others with a similar issue.

Thanks again Dave, you are awesome!
