Unable to find an operator implementation for coldfusion.compiler.ASToperator
I didn't find too much in the blog world on this error. I did find some things on the error message that I got when trying to look at the log files. There was a bug recorded on the Adobe site. The work around was to reinstall CF and reapply the update. After proceeding with that, which only took a few minutes, all was right with the world again. All errors disappeared.
Moral of the story? Maybe the update didn't install properly. I do remember getting an error message saying that the update didn't complete and that next time I should remember to shut down the CF services before applying the update. That could have been it. Either way... it works now.
