Alex.
Thank so much for responding.
As I am sure we all experience, sometimes we get so wrapped up into what we are doing,( tunnel vision), that we overlook the basic process of elimination. I have figured out the issue and wish to share it with you all. Although it was not the most obvious solution, I should have at least check this out.
As an FYI, the error I was receiving was "Subdirectory Add - Folders not found... HTML, IFRAME," These keys were added in my web.config, but were not on the sever.
For those of you using WebHost4Life services, please note that the FileManager's unzip and overwrite files option, which allows you to upload a zip file and extract it utilizing the server, does not work recursively. When I extracted my upgrade file and chose 'overwrite existing files', FileManager noticed that there was already a folder named "App_Code" and overwrote the whole thing, removing whatever was in that folder, even though there were files and/or folders inside that were not being replaced. This was continued with every folder that matched an existing folder.
Since the upgrade install package does NOT contain replacements for every file/folder in the original install, I was missing many files.
Perhaps I should have known this? Who knows? I am so used to Windows File Manager and/or CuteFTP, and , well, any other file manager I have ever used, that I nenver thought about it.
I used CuteFTP to upload the upgrade package instead and it worked perfectly. I am looking forward to diving into DotNetNuke. It looks awesome.
Thanks again.
