I have upgraded a website from Sitecore 7.2 rev 140526 to 8.2 rev 161129 using Express Migration tool. After doing all config changes, recompiling existing dlls with new sitecore dlls and other post upgrade steps, I was able to login and do functionalities in Sitecore back-end.
But when I view the public website, content inside placeholders does not renders to the webpage. But when I add Sublayout tag instead of Placeholder to the page and bind the presenatation component statistically it works fine. I cannot find any errors in the logs either.
Any suggestion to fix this?
