We tested creating and editing various tables, as well as loading front-end pages containing tables, and everything worked normally. * However, this doesn’t necessarily mean there isn’t an issue specific to your setup, so we’d like to investigate further. * First, could you please clarify a few things? - Does the fatal error occur immediately after updating wpDataTables Lite to 6.6.1.1, or only when you try to open a particular page? - Does it affect the entire WordPress website, including WP Admin, or only certain front-end pages containing wpDataTables? - If it happens on a specific page, is there a particular table or chart involved? - Which WordPress and PHP versions are you currently using? * The error you shared indicates that PHP exhausted its available 256 MB memory limit. However, the file referenced in the error (`class-wp-fatal-error-handler. php`) belongs to WordPress core and doesn’t necessarily identify what originally caused the memory exhaustion. * If possible, please check your hosting PHP error logs for any additional errors leading up to this fatal error. A complete error log could help us determine whether the issue originates from wpDataTables, another plugin, or something else in the environment. * For further testing, I’d recommend using a staging website. * Since rolling back to 6.5.1.7 resolved the problem, you can keep your live website on that working version for now. * If possible, create a staging copy of your website, update wpDataTables Lite to 6.6.1.1 there, and check whether the same issue occurs. * This would allow us to investigate without risking downtime on your live website. * If you can reproduce the issue on staging, please contact our main support team privately. * You can follow this guide to open a support ticket: * [https://help.wpdatatables.com/en/articles/39-how-to-contact-support](https://help.wpdatatables.com/en/articles/39-how-to-contact-support) * Even if you’re using the free/Lite version, you can select the Pre-purchase/Lite questions option and refer to this WordPress.org forum thread. * This way, we can collect additional details, review your environment, and, if needed, investigate the problem directly on your staging website. * We’d certainly like to understand why the newer version causes this behavior on your setup, particularly since the previous version works correctly. * Thanks again for bringing this to our attention! * Kind regards, Milos - This reply was modified 13 hours, 37 minutes ago by [Milos Jovanovic](https://wordpress.org/support/users/milosjovanovicwpdt/).
