I was having trouble uploading images with Firefox, so I followed a tip from this thread: [url=http://www.silverstripe.com/site-builders-forum/flat/16550]http://www.silverstripe.com/site-builders-forum/flat/16550, and updated the jsparty/SWFUpload files to the most recent release, v2.0.2. This enabled me to upload images and files in the "Files & Images" section.
However, in the Site Content section, when I click the Image Icon, and click the upload link, I was previously able to at least select the image I was hoping to upload, even though it wouldn't actually upload. Now, the 'upload' link redirects me to http://loaclhost:3000/#.
I've been comparing the new and old SWFUpload.js files, trying to find something that could've caused it, but I'm not great at javascript, so I've been having trouble (If that's even the problem.
I don't think the problem lies in the updated .swf file, because the problem didn't show up until I updated the .js file. I've reverted back to the original files and that hasn't fixed the problem.
I'm comfortable simply using the Files & Uploads section to upload images, but it would be nice to use the Site Content section upload these images.
Thanks for any ideas!
