My Saturday was spent attempting an upgrade to 4.3.5 (the newest version for which I had a corresponding version of the Oracle Data Provider from WebAcuity).  After making the source change that WebAcuity required, compiling, and uploading my files, I loaded the site and started the upgrade process.  After seeing a lot of messages printed to the screen (a lot of stuff about upgrading to this version, and then that version), I was redirected to the home page, which (if I recall correctly) is when everything went to Hell.

Basically, I started to see a lot of "object reference not set to an instance of an object" messages, mostly involving the membership provider.  I spent the next 6 hours or so trying to get the new version working, to no avail.  I think that there's something wrong with the way the Oracle stuff is configured in the web.config, but I had no luck in figuring it out.  I gave up on it at around midnight or so and went to sleep.

This morning, I decided that my first order of business needed to be rolling the site back to its earlier state.  I figured that would be as easy as uploading my backup of all the files and deleting a couple of entries from the database (like the version entries in the DNN version table).

I should know by now that nothing in life is ever as simple as you think it should be.  I uploaded my backup, deleted the new versions from the database, and "voila!" it's still broken.

Can anyone help me?  Can you point me in the right direction?  Is there any code documentation for this project? (I found a little documentation, but it seemed to be about 6 months out of date and sort of vague)  Is there some reason that my web.config file from two days ago would now not be working?

I'm in corporate Hell and am not allowed to touch the web server except through FTP, so please keep that in mind.

Thanks in advance for any help, suggestions, words of encouragement or commiseration.
