permission to use search engine

Hello,

What do I need to do in order to get permission to use the search feature? I am logged it, but when I click "Search" the site displays a message that says "You do not have permission to use the search engine. Return to the previous page or use search if you are looking for something specific."

A few seconds after I posted the above, I clicked Edit to fix a typo, and this message was displayed:

This post can no longer be edited because the maximum edit time has expired.

Return to the previous page or use search if you are looking for something specific.
