I have read many posts that have problems adding images to posts using the flash uploader with 2.5 and 2.5.1 and are getting a blank white box. I have tried several of the suggestions from this site but still have the problem.
I notice if I log into my site using http:/www.MYSITE.com/wp/wp-login.php I have the problem, but if I go through the start page by using http://www.MYSITE.com/wp and then select Log in from that page I don't have problems.
Has anybody else seen this? Is that first page setting up something on the flash to make it work or something that gets skipped by logging in directly?
