i am facing some issues regarding buy token feature of crowdsale i am using remix for ui and deployment just for testing after that i will use truffle and ganche it shows an error SafeERC20: low-level call failed and reverts

"low level token purchase DO NOT OVERRIDE This function has a non-reentrancy guard, so it shouldn’t be called by another nonReentrant function. "
