On one of my hosts, I am having a very irritating problem...
When I click 'Run' on the craw page, I get an error that doesn't stay long enough to read or copy, then it returns to the configuration page. Holding my cursor over that tab gives me a brief look at the error; but not that good.
It seems to say that there was an error retrieving the url specified [external links are visible to admins only]
It also seems to say that there was a problem opening a socket.
