I have an asp.net page that have a Web User Control WUC-1 (dynamically added), WUC1 is supposed to load another Web User Control WUC-2.
To accomplish this I am using Page.LoadControl(~/path to control) method. This method suddenly started to error as below

line 273 is exactly from where the above log is generated;
UserControl ucGal = (UserControl)Page.LoadControl("~/path/WUC-2.ascx");
I would appreciate if anyone can shed some light on it. It was working perfectly fine from YEARS until now
