Fix Event ID# 7043 Load control template file /_controltemplates/TaxonomyPicker.ascx failed: Could not load type

This is an error that's a little misleading. At first it might seem that the file is missing or that there is a permissions issue, but that's not the case. The problem is that there is a bad charater in the template file.
