Fix bep20 token problem

Hello guys, I have a problem. I have an own token which I had locked the liquidity, after that while launching it, you cannot sell, thats because there is no allowance to PancakeSwap, but once I approve it it still doesnt work, so basically, I tried to add allowance to the LP address, to the smart contract, and to the Router V2 of pancakeswap, none of them worked, please open the chat for more details.
