Here is a better alternative; install this plugin: https://www.ads-software.com/plugins/redux-developer-mode-disabler
I understand it has an outdated notice, and I’m working on getting access to fix it. It’s a few lines of code that disables Redux’s dev_mode
argument and will stop the display of that message. There are no security or incompatibility issues.
The reason the message occurs is that either the theme or plugin is using an older version of Redux embedded in the project and used a filter to disable customizer support (not the correct way to do it, I should add). The v4 plugin will override that old version but will cause that message you are reporting to appear while Redux’s dev_mode
is set to true (it should’ve been set to false before the developer released their project). The reason for the message is to catch the improper use of extensions built for Redux by other developers who are doing it wrong and are designed to appear only while dev_mode
is enabled.
Since we don’t know which plugin or theme is causing the issue, and since the issue isn’t an error that crashes the site, it’s easier to install the aforementioned plugin and simply get rid of the notice. Even if we knew which plugin or theme was the culprit, the developer would have to fix their own code, and isn’t something I could do anyway. Ideally, they should update Redux, but many seem resistant to the idea, so I no longer push it.
Good luck.
