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.

Fatal error: Call to undefined function add_theme_support()
Now I can longer access my admin or anything else.
Some suggestions in searches thought it may be a hosting problem.
Thanks
