Wordpress error during the API request

Here is a fix for a Wordpress error which we have seen.

Error: *An Unexpected HTTP Error occurred during the API request*.

If this error appears when trying to view plugins or themes, edit the wp-includes/http.php file.

Change this line:
'timeout' => apply_filters( 'http_request_timeout', 5),

to this:
'timeout' => apply_filters( 'http_request_timeout', 30),

Finally, refresh the Wordpress page.
