Hi, @dunoss.
Glad you reached out.
Warning messages like this display when your site has “Debug Mode” turned on. Debug mode is a method for developers to use to find issues in their code and compatibility problems with different versions of PHP (the server language WordPress uses). Debug mode is usually only used on development sites or non-live sites.
In your case, this warning message indicates that a specific class is deprecated.
In the meantime while we get the problem resolved, here’s how you can hide those warnings: in your wp-config.php file (which you can get to via SFTP or through your web host’s file manager) look for a line like this:
define(‘WP_DEBUG’, true);
Replace it with the following lines:
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);
@ini_set(‘display_errors’, 0);
Again, this method is normally only used for development, not on live sites.
If you need assistance with that, your web host should be able to help. Also, there is some official documentation on that: https://codex.projectdmc.org/WP_DEBUG
Feel free to reach out to us if you have any further inquiries or require additional assistance. We’re always happy to help!
