I've tried all I can but I can't get the Task,rewards,and themes to appear.
i have the base mod- Basic questing and the Standard Expansion both on and still nothing! help me!

Are you sure the expansion is loaded correctly? Check your in game mod list to see if it is there and you have downloaded the right version

I have the better questing-3.5.329 and standardExpansion-3.0.181 the two newest versions of the mod I could find

Did you happen to check that the 3.0.xxx versions of Standard Expansion are meant for 1.7.10?
Curse is lazy and just lists what is 'newer' but that may not be for the version of Minecraft you are using.

The version of Standard Expansion you need is 3.4.173.
Check your versions before downloading in future
