Just upgraded from 4.5.5 to 4.8.2 and it's throwing an error, no ideas why:

Could not load type 'DotNetNuke.Security.Authentication.AuthenticationController' from assembly 'DotNetNuke, Version=4.8.2.0, Culture=neutral, PublicKeyToken=null'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Hi Mark, No, I don't know why exactly, but I do know there have been new Authentication providers added between those two versions. From there error it looks as if you do not have the newest DotNetNuke.dll, so you may be able to fix the error by uploading the new DNN files again (at least the ones in the /bin folder).

I'm working on it locally, copied over the .dll files again and also installed ajax 1.0 in case it was something to do with that but no joy. this initially happened where I host the site, so I reverted it back to 4.5.5 and then downloaded it so I could try and upgrade locally, so not to sure where to go next. Any ideas?

Should also say that I've got a 4.8.2 version running locally which works fine, so 4.8.2 should be able to run on my system.

Just got it to work, don't exactly know how but think it may have been something to do with the web.config. I reverted back to the 4.5.5 version then copied the installation version of 4.8.2 over that installation along with the web.config file, replaced the machine key with my old one updated the database settings and it went ahead and upgraded no probs. Might be handy to know in case this happens to someone else. Cheers Mark

Thanks for posting back with your findings Mark. That was a good idea to just start over and try again. Sometimes things will happen in the middle of an upgrade that will be very hard to track down and fix.
