I have just installed the joomla 4 version of this template and when i update joomla I get the following error 

in xxxxx/libraries/src/Http/Transport/CurlTransport.php (line 169)

1.  
2. Code:

           // Set the cURL options.
3. Code:

           curl_setopt_array($ch, $options);
4.  
5. Code:

           // Execute the request and close the connection.
6. Code:

           $content = curl_exec($ch);
7.  
8. Code:

           // Check if the content is a string. If it is not, it must be an error.
9. Code:

           if (!\is_string($content)) {
10. Code:

                $message = curl_error($ch);

Can anyone please let me know what i am supposed to do, thanks

Hello,

You probably didn’t upload all the Joomla files completely (try reinstalling) or Joomla folders are not writable (check in System) or your web server is not 100% compatible with Joomla 4 (check this with hosting support)
