Default Play Store And Gmail not working

Since yesterday my play store and gmail stopped working.
I am on resurrection remix 5.0.7.
I think the problem is with adblock.I had installed rom toolbox and enabled adblock.Then without disabling adblock I uninstalled rom toolbox.
I dont know whether clearing hosts file will do it.
Is there any way to get play store running?I had this problem before and flashing a new rom fixed it but i dont want to wipe my data or flash a new rom now.
I tried deleting cache,data,updates of play store and play services but no luck.
Any solutions?
