Explicit data location for all variables of struct, array or mapping types is now mandatory. This is also applied to function parameters and return variables.
Add memory after string
function setmeme(string memory _url, string memory _name, uint _timestamp) public{

Select a different version of the solidity compiler. ^0.4.25 works for me.
The version of the solidity compiler has to be set both on the file and in the compile tab on remix(it is a drop-down menu).

You have to change the compiler version both on the file and also from remix. It is a drop-down menu on the compile tab. I have selected this:0.4.25+commit.59dbf8f1and it had no problem with your code.
