Warning! Error encountered during contract execution: out of gas

Question

On BSC Testnet I have deployed a token contract https://testnet.bscscan.com/address/0xE5bB5e6Cf65dBE0062d1EBa9e36e64F89e3f0638

And also a TokenSale contract https://testnet.bscscan.com/address/0xe6A01F088fE30e613D8449D6DA04196C90D5F255

Then I created a temporary DAPP with a swap function connected to my Tokesale contract. Here it is: http://kurt.bestcoinx.com/

The problem is that when I try to swap I get an error for example this transaction:

https://testnet.bscscan.com/tx/0x85b079d4351b16f8733e5b03dd97e7a8a4dfdddaa8037f3ce0c6a2ea9f4f16f7

with the error Warning! Error encountered during contract execution: out of gas

1. I have BNB in my Owner wallet
2. I have sent a sufficient amount of my token to the Token sale contract.
3. I have tried sending BNB to my Tokensale contract and it failed too.

I don't know what to do to get this to start working and I will appreciate it if anyone can check these issues out for me.

Thanks

Your WFT token's transfer method uses 65,994 gas for a transfer. The buyWithBNB method from the TokenSale contract uses it and not only it. The gas limit which you set is 50,000, that's why it's running out of gas. Try to set higher gas limit for buyWithBNB transaction.
