I am sorry to bump up this question. I believe I have sufficiently searched for similar issues on the internet but I was unsucessful. It is currently posing a blockage for me. I share resources with other people and I wanted to know if an upgrade of software requirements is needed. I do not have a computer science background, so I do not know if I might unintentionally break others code in the server trying to upgrade (or if I cannot upgrade by myself, I will have to convince the server admin that this is my problem say).
