If i am trying to edit the webpart, i am getting this error "Web Part Error: Sandboxed code execution request failed"
But the same code worked properly before two months, i didnt done any deployment activities from last 6 months..i dont know how it is possible ?
and the same issue happening during the javascript post back also
1) I cant able to restart the sandbox service because i am using office 365
2) it worked properly before march month, after the patch upgrade which is released by microsoft, i am facing this kind of issue..
can any one help to resolve this issue ?
