HTC 8X. Cant unblock blocked apps from running in the background

[PramodhN]

Hi, I recently blocked an app from running in the background in the background tasks. But now I want to unblock it but can't find out how. There is an checkbox that says app will be unblocked next time it opens but that doesn't seem to be happening how many ever times I try. How do I fix this issue?

Usually go into the app itself and re-enable the background task

If all else fails, try deleting the app and reinstalling it.
