Reverting to WordPress 5.9.3

  • Updated

Wordpress was updated automatically for many users in late May 2022 to Wordpress 6 (WP6). This broke compatibility with a number of more complex plugins like ShowcaseIDX and as a result, users have had to downgrade back to the supported 5.9.3.


It is not required that you roll your entire site back to a backup or restore point or anything like that, you would just be altering the version of the Wordpress Core module, which can be updated again later without issue after Wordpress 6 is more widely supported.

You will first need to check if your website was built using or They are different platforms with different instructions.

If your website is using, the steps to revert couldn't be easier! 

1) Install this plugin and activated it. Then access the settings from the plugins page


2) In the Wordpress target version box, enter 5.9.3 and save changes


3) Click “up/downgrade core” button to finalize the change


You can attempt to do the instructions above using the WP Downgrade plugin, but chances are that it will not work.

You can either do it manually, which may require a developer, or via the Activity Log. Instructions on how to do both can be found here

We have been clear in our documentation that the plugin works with WordPress Version 4.6, up to version 5.9.3 (the version prior to 6.0).

SIDX is composed of a large proprietary SaaS (software-as-a-service) platform that is delivered to agent/broker/team websites via a WordPress plugin. The core service is NOT down and is working 100% on sites running WP up to 5.9.3. Our engineering team is currently working on debugging the latest WordPress 6.0 update, to ensure full compatibility with Showcase IDX.

Many premium plugins, services, and themes often have hiccups with X.0 releases and even X.Y versions of WordPress, resulting in interruptions to services and business for those that upgrade before verifying compatibility. While we wish this was not the case, it is. This is why we recommend and closely follow best practices which advise not to update to a new iOS version when it is a new whole number (X.0), and to wait for the final bugs to be released. This is part of our strategic approach which allows us to work with a more stable and complete WordPress X.0 release so we can be sure Showcase IDX is fully compatible before certifying to our valued customers, like you, that upgrading will not result in interruptions to our services and their businesses.

This best practice is not isolated to Showcase IDX, but many other (and much larger, international SaaS) companies. Our team has worked through many, many WP updates for over the almost two decades we have been in business. We are intimately familiar, and in-tune, with the risks associated with major WordPress releases, and how to successfully navigate these, including timing. At the launch of the final version of this WP 6.0, there was nothing actually listed in the public changelog information, making it even more critical that we ensure we are provided with a more thorough list and work through each bug before confirming it is safe for our customers to upgrade their sites.

More simple plugins, or those with limited interaction with the core WP infrastructure, do not have this issue and are often not impacted by major (or even medium) WP updates. As the WP release is finally out and more documentation (both official and unofficial) is coming out, that will give our team more information to work with. Given the best practices mentioned above, not everyone is updating to WordPress 6 (as shown in the examples below), and while they will in time, it is critical for the continued success of your business that any updates we release integrate well and don’t break thousands of sites across our customer base.  


We do not have an exact ETA at this time, but rest assured that we are continuing to work diligently at debugging and confirming Showcase IDX compatibility with WordPress 6.0.
