Hi, i've been installing plugins on my site to use for twitter integration, ever since i started doing this i have been getting the folling 500 error on pages:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
I guess it's caused by a premature end of script headers. I dont know what this means and i don't know how to fix it. If anyone has any advice that would be great.
