I tried to create a token but screwed the sell fee

poo coin app says i have 100% sell fee and i want to change that but i can't. 0x9319991f12119b3effa9dde8d3d7395886088ab2

according to the contract itself the total fees is 12% and the contract you used has build in protected to prevent you going above 15%
Did you modify the the contract in some way to change the functionality?

To change fees after deployment you can call the functions:

setTokenRewardsFee
setLiquiditFee
setMarketingFee
