They are related to the updated functionality to allow for multiple payment gateways and seem to be only be happening if the plugin updated automatically. * We will be including the necessary modification to fix these warnings in the next update. In the meantime, if you deactivate and reactivate the plugin, it should clear them for you. * And, if you have any questions or issues specifically about the payment gateway functionality, please contact us directly via email or our site ([https://www.fivestarplugins.com/support-center/](https://www.fivestarplugins.com/support-center/)) as that is a feature of the ultimate version, discussion of which is prohibited here ([https://wordpress.org/support/guidelines/#do-not-post-about-commercial-products](https://wordpress.org/support/guidelines/#do-not-post-about-commercial-products)). - This reply was modified 4 years, 9 months ago by [jaysupport](https://wordpress.org/support/users/jaysupport/). * Thread Starter [hofercraft](https://wordpress.org/support/users/hofercraft/) * (@hofercraft) * [4 years, 9 months ago](https://wordpress.org/support/topic/wordpress-warnings/#post-14852581) * hi, thanks for reply. It doesn’t help, deactivate, reactivate, manual fresh upload,.. * Plugin Support [jaysupport](https://wordpress.org/support/users/jaysupport/) * (@jaysupport) * [4 years, 9 months ago](https://wordpress.org/support/topic/wordpress-warnings/#post-14856601) * In that case, until the next update is released, just roll back to version 2.2.11 of the plugin, which was before the payment gateway options were updated. * Plugin Support [jaysupport](https://wordpress.org/support/users/jaysupport/) * (@jaysupport) * [4 years, 9 months ago](https://wordpress.org/support/topic/wordpress-warnings/#post-14859892) * We just released version 2.3.5 with a further fix to eliminate the warning in the circumstances in which it was still showing. * Thread Starter [hofercraft](https://wordpress.org/support/users/hofercraft/) * (@hofercraft) * [4 years, 9 months ago](https://wordpress.org/support/topic/wordpress-warnings/#post-14864169) * Thanks, that solves most of the warnings. However, this one is still there: * `Warning: Undefined array key "rtb-bookings" in /var/www/html/wp-content/plugins/ restaurant-reservations/includes/Dashboard.class.php on line 66` * Plugin Support [jaysupport](https://wordpress.org/support/users/jaysupport/) * (@jaysupport) * [4 years, 8 months ago](https://wordpress.org/support/topic/wordpress-warnings/#post-14868145) * It’s not really possible for that array key to not be found. It’s definitely defined in the plugin. Unless you have something else that is interfering with it or changing the key to something other than rtb-bookings. And the only thing I can think of that might do something like that is if you had a translation plugin that, for some reason, was changing it. * The first thing to check is, if you go to the settings page in the plugin admin, does it have the correct styling, or does it have no styling at all? The line for which you’re getting the warning relates to where the admin styling gets enqueued. So, if you’re not getting any styling, that would be a good indication that the array key has been renamed.
