This issue is causing me headaches on multiple sites on multiple servers with different plugins and different themes.
Running WordPress 3.1.1.
At home I can upload pictures through the media upload fine. Not a problem.
At work however, (and where I need to be able to use WordPress most of the time), it just hangs on the 'Crunching' stage, and eventually times out. This happens on the flash uploader and the basic browser uploader.
It happens on work desktop computers and my personal laptop on the work network (but without any of the work security software). The very same laptop works fine for uploading on my home network.
I can only assume it is something to do with the work firewall. But how would it block uploads yet allow logins, posts etc all to be made?
I can take this to our IT department, however they get a bit difficult when it comes to these things, so I'd like to be make sure it is definitely being caused by the firewall, and be able to be confident in asking them what I need them to do?
Can anyone shed any light?
