DasBlog 1.7 and Free Text Box
Clemens mentioned to me that after upgrading in-place to DasBlog they are seeing a BLANK page when visiting the Administration "Edit Entry" page.
This appears to be some left over schmutz somewhere in a Temporary ASP.NET Files folder as it relates to the upgraded version of FreeTextBox that DasBlog 1.7 included. Somewhere in the temp world the FTB versions aren't lining up.
I had this problem myself, and I fixed it by doing a fresh deploy of my bin folder. I backed it up, delete all of bin, and redeployed all the application assemblies and resource assemblies. Also confirm that you've got the latest versions of all ASPX and ASCX files.
