Hi, yesterday I installed a DNN 5.1.0 in my localhost and... no problem... Worked like a breeze... Today, when loggin in... error message: Parameter count does not match Parameter Value count. I crawled the forums but this kind of issue is usually associated with older DNN versions. The only modules I installed if I can remember were the UDT (forgot its new name), text/html, map and some others... If anybody knows how to solve this... I appreciate. Thanks.

I just attempted the same update , but from 4.9.1, and it failed several times -- first failure occurred at 5.01.00:

00:00:03.375 -   Executing Script: 05.01.00.SqlDataProvider Error! (see 05.01.00.log for more information)

followed by a string of failures:
00:00:18.468 - Installing Optional Modules:

Then, when it is done, it returns to the default.aspx and returns the parameter count error:
 

Parameter count does not match Parameter Value count.

So, the upgrade package didn't work well at all on a localhost -- the previous installation was basically nothing -- just one page other than the default install page.  I use this to test the install and update process before unleashing it on a live site and then having to explain why things aren't working as expected.

Any guidance from you or others on how to proceed would be appreciated and the insights shared on this forum.

A few more details.

The DNN 5.1.1 that I installed was the starter edition.  (Enough source to write modules & skins, but not all of it).
There are no direct calls to the UpdatePortalAlias stored procedure in the source that I have.
In my sql database, the UpdatePortalAlias shows four parameters...

@PortalAliasID                       int
@PortalID                                int
@HTTPAlias                           nvarchar(20))
@LastModifiedByUserID      int

...I am out of ideas as to what to do next with the source that I have, and I don't have VS2k8, so more source won't help.
I guess I'm going to uninstall and fall back a few versions.
I'll let you all know how it goes.

Peace,
Colt
