Hello,
I installed the CF hotfix APSB13-10 hotfix to my CF 9.00 installation. I am aware of the three different versions for 9.01 and 9.02 and used the version for 9.00. In addition, as I had already installed the previous security patch, I used the version that was designed for that.
However, after patching I can no longer view the CF Admin. The page renders, but is blank and only has the following HTML:
[Ok, I can't paste it, but basically it's all empty tags for HTML, HEAD, and BODY tags.]
The websites that run on my server are functioning okay, but obviously without the CF admin I will have trouble in the future if I need to make any changes.
In addition, backing out the changes did NOT fix this, so at this point I am stuck. 
I am running MS Server 2003 R2 with IIS 6.
Does anyone have any suggestions for this?
