Server Error when trying to go to Install Plugin Page

Hi All.

When in Admin mode and I want to try and search for a plugin, it gives me a server error, with the option that it might be my server settings or wordpress.org. (My guess is that something has changed in my setting without me knowing of it)

See attached link for picture of the dashboard error

Have you any suggestions to what might happened and what I can do to correct it?

[No bumping, thank you.]
