I have a SP2010 wsp that contains multiple features all are scoped "web" all was working fine. But suddenly one of the feature stopped activating by default on deployment though all other features are activated. I checked for the "Activate On Default" property which is set to true. But it seems to have no effect on activation.I can go to features list in my site and activate the feature manually and there is no error and feature performs what its intended to.
Tried to even debug the feature receiver code (using VSSHost) but that too doesn't work.
Any help will be appreciated.
