Thank you for your quick response. I will send the bug report in a moment, but I don’t think it’s a migration issue. I removed all files from the host, removed everything from the database and started totally from scratch. Installed WordPress, installed NextGen Gallery and… same thing, meaning blank pages for settings and “You browser doesn’t have Flash, Silverlight, HTML5, or HTML4 support.” under Add Gallery / Images.
I will try looking for the directory separator stuff later today also.
