Gday all,

I've upgraded a website from 3.3.7 to 4.5.1. I've transferred over the NewsArticles tables, changing ModuleID values, etc. All seems fine except for a couple of things. When I click on Categories, the correct number of articles are shown. When click on a category, I receive the following error:

A critical error has occurred.
Multiple controls with the same ID 'Template_379' were found. FindControl requires that controls have unique IDs.

The other issue is that not all articles are displayed in the listing. I've checked the db and all have the correct ModuleID. This is a big one for us...

All help is appreciated!

Thanks
