However, when I try to activate, i get the error: Fatal error: Can’t use function return value in write context in /home5/threeco5/public_html/wp-content/plugins/user-registration-content-restriction/includes/class-urcr-shortcodes.php on line 38 How can I fix this? March 26, 2018 at 4:53 am #1619 sanjeev3Member Hello Khurram Aziz, The error appears for PHP<5.5. We recommend using PHP version >5.5. However we will also make it compatible to some lower versions too. Regards, WPEverest Support Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
