It may be more helpful to go the Elite discord, and go to the #walletsupport channel and see if someone can help you.  It's easier to communicate in real time in there.

However, I can tell you that you do not need to add "staking=1" to the conf file in the Elite wallet to stake. It's set up to stake once it's fully synced automatically.  And to the point of someone else that responded, it does have to unlocked for staking.

Is the up-arrow in the bottom right corner of the wallet not green? Also, depending on how many coins you have, staking will take longer with smaller balances.
