I have a network of sites created that I use for a Public High School to update school events. I have a main site and then subdirectories for Band, Drama, Newspaper, and Guidance.
I uploaded a large pdf file a few days ago and an hour later the admin of the Band site tried uploading a video and got an error message, "(Name of File)” has failed to upload due to an error. Sorry, this file type is not permitted for security reasons.
At the time, I was at WordPress 3.1 so I updated to 3.1.1. No luck. Then I had quite a few updates for the plugins and one for a theme, so I preformed all the updates. Still no luck.
These network of sites were created back in November and have been working fine for a while. I don't think the htaccess file would have caused this problem, but the site is housed on a School District central server. I can ftp to the site, but I can't upload any file type to the wordpress page. Any help would be greatly appreciated.
