Title: Warning: Undefined array key Last modified: January 2, 2023 --- # Warning: Undefined array key * Resolved [karlemilnikka](https://wordpress.org/support/users/karlemilnikka/) * (@karlemilnikka) * [3 years, 5 months ago](https://wordpress.org/support/topic/warning-undefined-array-key-13/) * After upgrading to Spectra 2.1 or later, I often get a warning at the top of our site with the following message. This is not an issue with Spectra 2.0.16 or lower. * ```wp-block-code Warning: Undefined array key "paddingLeft" in /public_html/wp-content/plugins/ultimate-addons-for-gutenberg/includes/blocks/post-grid/frontend.css.php on line 70 Warning: Undefined array key "paddingRight" in /public_html/wp-content/plugins/ultimate-addons-for-gutenberg/includes/blocks/post-grid/frontend.css.php on line 71 ``` * The warning shows up even though debug isn’t enabled. It might be related to our usage of WP Rocket since clearing the cache removes the warning for a while. The site is running WordPress 6.1.1 and is powered by PHP 8.0. File generation is enabled for Spectra assets.

We do everything we can to help, and we are happy that you found our support helpful today. * By the way, I was wondering if you might be able to help us as well. If you don’t mind, I’d appreciate it if you could give Spectra a 5-star through our [profile on W.org](https://wordpress.org/support/plugin/ultimate-addons-for-gutenberg/reviews/?filter=5#new-post) and tell others how you feel about it. * This would help other users make a comfortable decision while choosing the theme and be assured of our support. * Please spare the time to let me know if/when you leave the review so I can say mine thank you! * Thread Starter [karlemilnikka](https://wordpress.org/support/users/karlemilnikka/) * (@karlemilnikka) * [3 years, 4 months ago](https://wordpress.org/support/topic/warning-undefined-array-key-13/#post-16439966) * I’ll leave a review when the product is a little more mature. Based on all the update issues we’ve had for the past couple of months, it doesn’t feel like a stable plugin yet so my review wouldn’t be fair. * [BSF – Judith Pete](https://wordpress.org/support/users/judith0/) * (@judith0) * [3 years, 3 months ago](https://wordpress.org/support/topic/warning-undefined-array-key-13/#post-16478126) * Hello [@karlemilnikka](https://wordpress.org/support/users/karlemilnikka/), * Thanks for writing back. * Thanks for sharing your feedback with us. We have worked on the various issues that users have raised with our plugin to the level we are confident it is stable, however we also appreciate feedback as it helps us improve on the areas highlighted by our users, which in turn makes our product better. * Allow me to mark this as resolved. * Please feel free to open a new thread in case of any other queries. * Regards. * Judith.
