I installed a beta of SS3, which had a few problems. One of which is images don't upload. On the same server, I've since created sites with the latest SS3 and it all works just fine
With the first site, I just uploaded new version of the 'csm' and 'framework' folders, and set all the assets folders to '777', but it still won't upload the images.
I'm wondering how best to fix this - is there a recommended of reinstalling from scratch, and then bringing back all the uploaded assets and database, and mysite content?
or is there any way I can debug / fix the image upload?
The problem is I click the tree icon in the html text editor, choose the image files, but nothing happens. If I upload through the Files area it uploads fine...
