I try to update the Base module and get the following message: Warning: Use of undefined constant CURLOPT_ACCEPT_ENCODING. What can I do?

PHP constant CURLOPT_ACCEPT_ENCODING was added to the Base module in v.1.12.16 and is declared in PHP library curl/curl_d.php.

If you see this error message, it's likely that the PHP version is a bit outdated. Therefore, it's recommended to check if the constant is declared in the library curl/curl_d.php. If not, please consider upgrading the PHP version. In case the constant is declared, but the message is still shown, you may ignore the warning as it doesn't affect the installation process.
