Hi,

DNN newbie here.

Upgraded my company's web site from 4.9.1 to 5.1.1.
I unfortunately didn't save/screenshot the upgrade output, but I do remember the upgrade script failing on all the DataProvider scripts.

Now, post-upgrade, when accessing the site, everything but each page's dynamic content appear to be loading-- dynamic menus load correctly, just not the page copy, which is blank.

Error message appears upon admin login where page copy should appear:

DotNetNuke.Services.Exceptions.ModuleLoadException: Parameter count does not match Parameter Value count. ---> System.ArgumentException: Parameter count does not match Parameter Value count. at Microsoft.ApplicationBlocks.Data.SqlHelper.AssignParameterValues(SqlParameter[] commandParameters, Object[] parameterValues) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteReader(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Modules.HTML.SqlDataProvider.GetHtmlText(Int32 moduleId) at DotNetNuke.Modules.HTML.HtmlTextController.GetHtmlText(Int32 moduleId) at DotNetNuke.Modules.Html.HtmlModule.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---
 

I'm pretty lost with how to remedy this, so would be extremely grateful if anybody could offer some immediate advice.
