Trouble upgrading from 4.0.2 to 4.6.2

The title summarizes the problem.

I start at 4.0.2

Upgrade to 4.4.0 is fine.

Upgrade from 4.4.0 to 4.5.0 is fine.

I then try to upgrade from 4.5.0 to 4.6.2 and get this error (after installing the upgrade files, modifying web.config, and then browsing to the site). Any help will be appreciated ...

Re: Trouble upgrading from 4.0.2 to 4.6.2

Hi Joe,

Your exception is telling us that DotNetNuke is choking when it tries to create its DataProvider. Check your web.config to ensure that you are specifying the DataProvider that you intended (almost certainly DotNetNuke.Data.SqlDataProvider) and that its assembly exists in your bin directory. The file you should look for is DotNetNuke.SqlDataProvider.dll.

Re: Trouble upgrading from 4.0.2 to 4.6.2

Thanks. I understand your answer, but I think that there something going on that I really don't understand.

I started with a version that was 4.0.2. I can upgrade to any version up to 4.5.5. When I try to upgrade to 4.6.0 or anything higher, the error that I mentioned in the original post occurs. So ... there's something going on that I'm not doing correctly in my web.config file. But, I'm making the same sorts of changes to the file -- copying over the connection strings, machinekey, etc. I've checked multiple times, but I can't see any differences in the dataprovider section of web.config.

The fact that this happens going from 4.5.5 to 4.6.0, but didn't happen on other upgrades getting to 4.5.5 indicates that the is some change that I'm not catching.

Does anyone remember a change at the 4.6 line?

I did see a note about a similar error reported in Mitchel Sellers' blog. That problem appeared to be with a database prefix, but I haven't been using one ...

Re: Trouble upgrading from 4.0.2 to 4.6.2

Hi Joe,

You're analysis seems correct. If you look at the inner exception you're receiving, DNN's Framework.Reflection.CreateObject is trying to create an object of type null, and thus the throw. This pretty much excludes an assembly / file problem (I would expect to see a "type not found" or "assembly not found" in that circumstance).

So you'll need to figure out why DotNetNuke is asking .NET to create an object of type null. The most obvious place here is exactly where you suspected, in your web.config. I looked at my archived 4.5 web.config and do not see any schema changes in the DataProvider section between it and a 4.8.1 version. I have skipped 4.6, so I can't state with authority that nothing changed, but it seems unlikely that something would change here and then change BACK by 4.8.

Maybe try posting your DataProvider section. Also, if you have access to a debugger on your DNN machine, this would probably be a time to fire it up. You're looking to break in DotNetNuke.Framework.Reflection.CreateObject when objProviderType = "Data". A quick look at the data provided to this method would probably immediately make it clear where the problem is. The provider pattern is pretty fragile when it comes to small, difficult-to-notice configuration issues, so it's very likely that we're looking at something small here.

Re: Trouble upgrading from 4.0.2 to 4.6.2

AFAIR for DNN 4.6.x you need to make sure, that the connection strings in web.config do not contain trailing ; semicolon.

Besides you do not need to perform each individual upgrade, from 4.5.x simply install 4.8.2 and call the site.
