I'm using wordpress version 3.1 and if I try to upgrade any plugin on any of my sites I get the error message
error: An Unexpected HTTP Error occurred during the API request. Not by upgrading automatically, but manually upgrading through the dashboard plugin area I guess I mean
I've google for a solutions, to no avail. I've gone into my
class-http.php file and changed this code
'timeout' => apply_filters( 'http_request_timeout', 5), to
'timeout' => apply_filters( 'http_request_timeout', 30), Also tried request time out at 60.
Also downloaded Core Control Plugin, went into External HTTP Access and disabled each of those 4 PHP HTTP Extension/Transport options one by one and still same problem.
