My DNN Portal contains some LinkClick anchors and It has a format like 

"/LinkClick.aspx?link=828&tabid=642"

I think the value of link is represents the target tabid and the value for tabid represents current tabid

These anchors not working correctly now and when I press on such links it redirects me to different page which contains  "HealthMonitoring" Module.

When I tried to add new LinkClick in My Portal to the same page that I'm trying to access by using the first ULR .. LinkClick has different URL Format now which is something like that
"/LinkClick.aspx?link=%2MyPage.aspx&tabid=642"

I think the change related to the value of link it represents page name now instead of tabid

So anyone know the cause of that and why my old anchor links with old URL Format not working well ??
