Hello,
I'm getting this fatal error lately. Not always but mainly when trying to open the plugins menu in Dashboard.
PHP Fatal error: Cannot access private property AWPCP_WPError::$wp_error in /wp-content/plugins/another-wordpress-classifieds-plugin/includes/helpers/class-easy-digital-downloads.php on line 82
Everything seems to work fine though.
