 * Hi,
 * I could not edit remove my previous topic. Shouldn’t Rank Math be compatible 
   with Php 8? I get a lot of warnings running the wizard:
 * [..]/plugins/seo-by-rank-math/vendor/cmb2/cmb2/includes/types/CMB2_Type_Multi_Base.
   php34
 * ErrorException (E_DEPRECATED)
    Required parameter $i follows optional parameter
   $args
 * It’s mentioned before:

 * Array to string conversion
 * [..]plugins/seo-by-rank-math/vendor/cmb2/cmb2/includes/CMB2_Types.php
 * $suffix contains this?
 *     ```
       array(2) { ["label"]=> string(256) "
       Easy
       For websites where you only want to change the basics and let Rank Math do most of the heavy lifting. Most settings are set to default as per industry best practices. One just has to set it and forget it.
   
       " ["value"]=> string(4) "easy" }
       ```

 * Hello [@smeedijzeronline](https://wordpress.org/support/users/smeedijzeronline/),
 * Thank you for contacting the support and sorry for any inconvenience that might
   have been caused due to that.
 * It seems to be working fine on our end.
 * Assuming you are using the latest version of all the plugins, themes, and WordPress(
   please update if not yet), it would seem like a conflict with one of the plugins
   or the theme you are using.
 * To determine that, please follow this troubleshooting guide:
    [https://rankmath.com/kb/check-plugin-conflicts/](https://rankmath.com/kb/check-plugin-conflicts/)
 * Only the site admin would know and your users won’t be affected by this troubleshooting.
 * You can follow this video tutorial as well:
 * If that does not help, please send the report from Dashboard >> Rank Math >> 
   Status & Tools >> System Status
    **and the screencast showing you following the
   above troubleshooting guide.**
 * Looking forward to helping you.
