[Plugin: WordSocial] Request Token Errors

I have wordsocial installed in a subfolder of my domain. I can’t get twitter and Linkedin to work. The error I am getting is below, how to fix? Anyone get this to work and where, how?

Connected to facebook ok…but

for Linkedin: Request token retrieval failed

For Twitter: There is no request token for this page. That’s the special key we need from applications asking to use your Twitter account. Please go back to the site or application that sent you here and try again; it was probably just a mistake.

Thank you in advance.
