S4FE is a freely accessible, blockchain based search engine dedicated to the protection of property.
It provides a global network for the registration of items and the recovery of lost or stolen property.

Ownable.initialize(address)._sender (#471) lacks a zero-check on :
- owner = _sender (#472)
Check that the address is not zero.

S4FE.transfer(address,uint256) (#613-618) compares to a boolean constant:
-require(bool)(msg.sender == owner || transferLocked == false || transferWhitelist[msg.sender] == true) (#614)
Remove the equality to the boolean constant.

Pragma version^0.4.24 (#9) 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.
