Contract ticker (Pig Queen) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
DevErc20.transferFrom(address,address,uint256) (#125-136) compares to a boolean constant:
-require(bool)(allow[_from] == true) (#129)
Remove the equality to the boolean constant.
Additional information: link
SafeMath.div(uint256,uint256) (#66-71) is never used and should be removed
SafeMath.mul(uint256,uint256) (#57-64) is never used and should be removed
Remove unused functions.

Pragma version^0.4.26 (#17) allows old versions
solc-0.4.26 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
