We are recommending to all our clients they upgrade their WordPress install to the latest version of WordPress which is 5.5.1.
In that notification Email, we recommend NOT upgrading to 5.5.0 and wait until 5.5.1 arrives. WordPress 5.5.1 has arrived, and we now recommend you upgrade your WordPress install to the latest WordPress version. Below is a checklist of going about upgrading.
If you have KartHost Managed WordPress hosting service, we will immediately be upgrading your website. Upgrades will happen over a course of 2 weeks, Sept 3 - September 17, 2020. We will be following the same steps as outlined below. Note: If you have our EZWP Complete package, you automatically have KartHost Managed Hosting.
Check List for Upgrading Your WordPress Site
(Note if you have KartHost WordPress Managed Hosting or KartHost EZWP Complete package, we will be handling your upgrade for you).
 Upgrade all Plugins (even deactivated plugins). Note: if a plugin is deactivated and you have no plans to use it in near term, delete that plugin)
 Upgrade your Theme(s) - Note: If you have multiple themes that are not being used (with exception of your Child Theme and a standby 'back up theme', we recommend you delete those if no plans to use them anytime soon).
CAUTION: If you have a custom theme that was created by a WordPress developer you will more than likely not be able to upgrade it without losing all your customization. Ask your Developer that created your custom theme as to the best course of action for your situation.
CRITICAL: If you are using an OLD theme (not necessarily custom) that is no longer supported, we CAUTION you on the upgrade of WordPress to 5.5.1. Make sure you have a backup of your site and if you need a Development Site to TEST the upgrade, open a WordPress Help Desk ticket and we will be happy to clone your site so you can test your Upgrade.
If You Have a Complex Site: If you have a Complex site, like eCommerce, Online Courses, any type of complex processing, we recommend you TEST your upgrade request a Clone Copy of your site.
 Make a BACKUP! – This can not be stressed enough. The recommendation is to upgrade your Theme and Plugins. Then Make a Backup of your site in case the upgrade fails for any reason.
