Error : Load control template file /_controltemplates/TaxonomyPicker.ascx failed

Error 7043 "Load control template file /_controltemplates/TaxonomyPicker.ascx failed"

Answer :

This is not causing any issues except for a wrong ULS log message a single time in a web application process life time, the exception is caught and that template file is skipped. This message should be treated as log noise and can be ignored.To change this behavior:

1. Navigate to /14/TEMPLATE/ControlTemplates/TaxonomyPicker.ascx user control
2. Open the user control in a text editor and locate the first line
3. Find the character string , and replace with a comma ‘,’ (without quotes).
4. Save the user control
