While we should be able to reproduce it on our end, please check the troubleshooting steps described below and let us know the result. * **Part A:** It could be related to the version of PHP; while WordPress recommended using PHP version 8.1.x, please try to check the issue with PHP version 8.1 – you can ask your host provider to change the PHP version on your host. * **Part B:** For troubleshooting plugins, please do the following steps and let me know the results: * 1. Head over to WP Dashboard > Plugin. 2. Deactivate all plugins. 3. Then, first, activate the Ocean Extra plugin. 4. Check your issue. 5. Then, activate your plugins one by one 6. After activation of any plugins, check your issue * Note 1: You can try troubleshooting on the staging website/or on a fresh installation. * Note 2: If you have any cache plugin or server cache(CDN / Browser Cache and Cookies and …), you need to clear its cache contents or disable them to see your changes. Also, remember to click on the regenerate all assets file and data in Elementor > Tools(if you have Elementor). * **Please Note:** Since it’s just a warning and does not hurt your website, you can turn off your WordPress debugger to hide it: [https://wordpress.org/support/article/debugging-in-wordpress/#wp_debug](https://wordpress.org/support/article/debugging-in-wordpress/#wp_debug). However, this topic has been forwarded to the developer team to check it deeply, and if we find the issue, we’ll fix it in the next updates. * Also, if you find out how we can reproduce the issue, please share your steps to arrive the issue on a fresh WordPress. It’ll help us to solve this warning asap. * Please keep us posted.
