Title: Fatal error when using shortcode [arm_membership] Last modified: June 5, 2025 --- # Fatal error when using shortcode [arm_membership] * [lisannedevries](https://wordpress.org/support/users/lisannedevries/) * (@lisannedevries) * [11 months, 1 week ago](https://wordpress.org/support/topic/fatal-error-when-using-shortcode-arm_membership/) * Hello, * I’m using the free Lite version of ARMember and I’ve encountered a bug related to the `[arm_membership]` shortcode. * When I place this shortcode on a page (with or without parameters), it works correctly for users who **do not** have an active membership plan. However, once a user purchases a plan, the page throws a fatal error and becomes inaccessible. * To troubleshoot, I performed the following steps: - Deactivated all plugins except for ARMember Lite. - Switched to a default WordPress theme (e.g., Twenty Twenty-Four). - Cleared cache and checked server logs. * Despite having all of my plugins and theme up to date, the issue still occurs, confirming it’s not caused by a conflict with other plugins or the theme. * Here are my site details: - WordPress Version: 6.8.1 - PHP Version: 8.2.28 - ARMember Version: (Lite – latest available) * Please visit this page for a example of the problem: [https://docs.ownyourgoals.nl/4713-2/](https://docs.ownyourgoals.nl/4713-2/) * Below is the error I found in my error log: **Fatal error**: Uncaught TypeError: Cannot access offset of type string on string in
