We have custom web part which pulls data and shows the result. Suddenly after the SQL patch update web part threw an error shown below
"This page has been modified since you opened it"
We did a temporary fix by making MSO_PageHashCode value to null. We did Windows Patch update before but didn't faced this weird issue
Can somebody please help us getting exact root cause for getting this issue? Do MSO_PageHashCode has any relation with SQL patch update?
