Well I'm enjoying my experience of WordPress 2.5 already. The admin interface is so much cleaner, and it does so many things better than before!

I did however have one small problem. When trying to add media using the new media interface, I kept getting HTTP errors. After a bit of searching around, I discovered it was due to the mod_security Apache module.

Not wanting to disable it entirely, I discovered that it is possible simply to disable the POST filter, which allows the gallery to work. Simply add the following to the .htaccess file in the root folder of your blog:

<IfModule mod_security.c>SecFilterScanPOST Off</IfModule>

This works for me, so I hope it works for you!
