curl_exec() has been disabled for security reasons in WordPress 2.7

The latest version of WordPress 2.7 requires curl_exec() function. However, for security reasons, many hosts do not allow to use this function and due to this your wordpress blog will not function properly. There is an alternative available to use WordPress 2.7 without enabling curl_exec() function.

First download this plugin and install it:

After you activate it, you’ll see a list of what transports WordPress detected as working at the bottom of the admin screens (in the footer). Once you know these, you can deactivate and delete the plugin.

If you are not able to activate the plugin you can ignore the above step.

Now, open functions.php which is in your theme directory and add the following code:

function block_transport() { return false; }
add_filter('use_http_extension_transport', 'block_transport');
add_filter('use_curl_transport', 'block_transport');
add_filter('use_streams_transport', 'block_transport');
add_filter('use_fopen_transport', 'block_transport');
add_filter('use_fsockopen_transport', 'block_transport');

That will block all five possible transports from working. Now just remove the add_filter line on the transport that you want WordPress to actually use.

Added: You will need to add above code in php block and put at the end of function.php file.

    Thanks for your alternative solution to this issue. I was in big trouble as my host had dined the request to enable this function on the server and this has helped me to fix my blog. Thanks !!

    I was really thinking to switch my host as they have disabled curl_exec() function and I had upgrade my blog to WordPress 2.7. But I have found this solution to fix the issue without enabling curl_exec() function. Thanks !!!

    might of been an idea to actually say where in functions.php you put that code.

    You will need to add above code in php block (between ) and put at the end of function.php file.

    This has been fixed in WordPress 2.7.1. Now we do not require to modify function.php if curl_exec() function is disabled on the server.
