It seems that I can no longer remove or add pages to my portal or at least not in the usual manner. When I add a new page it all seems good and nice, if I add a module or remove one from that new page then suddenly Im moved at the splash page and I can no longer see that page on the menu. Then the strange things start. If I try to delete the page from the pages admin then some times I do see the page and I can delete it, other times I cant see the page but I can see it in the database and I also get an error. Also if I remove the deleted pages from the recycle bin at first it shows that all have been removed but If I empty the bin again then I get all the old files back.

DotNetNuke.Services.Exceptions.ModuleLoadException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index ---> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.ArrayList.get_Item(Int32 index) at DotNetNuke.Modules.Admin.Tabs.Tabs.DeleteTab() at DotNetNuke.Modules.Admin.Tabs.Tabs.cmdDelete_Click(Object sender, ImageClickEventArgs e) --- End of inner exception stack trace ---

So far it seems that existing pages all function as they should, modules can be added.

would appreciate any help possible before nuking the server

I was using 4.5.5 but I run the 4.6.2 upgrade yesterday. Do u think that I should try and locate the problem or is there a way to fix it without messing with the code/db ?

you should have a look at the tables in your database, I don't see another option.
