Undefined Variable post in SolidPostLikesWoo.php on line 20

Hi @silvanarnet,

Thank you for your message.
This sounds like a PHP warnings / notices, not full error. They are for developers only and they must not display on your site to begin with.

You can disable them by editing your WP_DEBUG settings in your wp-config.php.

Here is a short tutorial:

If it does not work with just the WB_DEBUG set to false:

try this:

// Disable WP_DEBUG mode
define( 'WP_DEBUG', false );

// Disable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', false );

// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );

// Do not use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', false );

Regardless we will try and remove the notice for the next version.

Kind regards,
