Unable to complete malware scan – 503 error

Hello, @lornajc

We have a solution for you to fix this issue.

Please make sure you are using the latest version of our Security plugin. If not, please update it. The guide is here: https://cleantalk.org/help/update-wordpress-security

Then open the wp-config.php file. You can find it in your website folder. And add the following: define(‘SPBC_ALLOW_CURL_SINGLE’, true);

Usually it is added after WP_DEBUG.

This method will allow the scanner to work, but slower.

Did it help?
