Page management is in error.

Upgraded from 3.1.0 to 3.2.2, all seemed to have gone well, except for the fact that i can't add/delete/edit any pages; although modules can be added/deleted/edited?

Existing content is fine, as went the upgrade, but page management returns the following error message:-

Error: Page Management is currently unavailable.
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.ExecuteNonQuery(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Data.SqlDataProvider.UpdateTab(Int32 TabId, String TabName, Boolean IsVisible, Boolean DisableLink, Int32 ParentId, String IconFile, String Title, String Description, String KeyWords, Boolean IsDeleted, String Url, String SkinSrc, String ContainerSrc, String TabPath, DateTime StartDate, DateTime EndDate, Int32 RefreshInterval, String PageHeadText) at DotNetNuke.Entities.Tabs.TabController.UpdateTab(TabInfo objTab) at DotNetNuke.Modules.Admin.Tabs.ManageTabs.DeleteTab(Int32 TabId) at DotNetNuke.Modules.Admin.Tabs.ManageTabs.cmdDelete_Click(Object Sender, EventArgs e) --- End of inner exception stack trace ---

Would someone be kind enough to give me advice/solution.

Many thanks.
