Widget error after upgrading to 5.8

Hi, @mikealan

First things first:

To provide a link to the relevant page I would have to provide a temporary login which can be done if required.

Please give this a read https://www.ads-software.com/support/guidelines/#the-bad-stuff
Never share any login info on these forums and if someone asks it, use the Report button in the sidebar. ??

Then, you could try installing the Classic Widgets plugin to disable the new widgets screen in 5.8, and revert back to the original Widgets screen. It might fix your issues: https://www.ads-software.com/plugins/classic-widgets/

PS: Always make sure you have a backup! ??

Kind regards!

Hi @vladytimy, Thanks for your advice.
My site is backed up on a regular basis so I could literally revert to the previous version if no solution is found and block updates.

Kind regards

If “classic widgets” works for you, then see if you can find out whether the issue is with a plugin or your theme. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

I have 38 active plugins helping to run a fairly large school alumni site under construction and I need to get this sorted asap.

Out of these 38 plugins there are 6 that give the following error each tested separately with all other plugins, css and added code deactivated:
Notice: wp_enqueue_script() was called incorrectly. “wp-editor” script should not be enqueued together with the new widgets editor (wp-edit-widgets or wp-customize-widgets). Please see Debugging in WordPress for more information. (This message was added in version 5.8.0.) in /home/********/********/build2/wp-includes/functions.php on line 5535
And they are:
1. Advanced Editor Tools (previously TinyMCE Advanced)
2. Advanced iFrame
3. Block Background
4. Shortcodes Ultimate
5. Smart Slider 3
6. Ultimate Addons for Gutenberg

My question is: might this error be a bug in the above plugins, a bug in the latest WP upgrade or some other reason and how might I solve it?

Thanks in advance for any help

Just to add, in the mean time, as Steve Stern suggested, I shall use the Classic Widget editor but still wll welcome replies to the above problem.

Cheers

Thank you for debugging this. Although the Classic Widget is a solution, it’s just a patch.

My question is: might this error be a bug in the above plugins, a bug in the latest WP upgrade or some other reason and how might I solve it?

The problem is that some themes and a few plugins have compatibility issues with the new Widgets screen. So the goal is to identify those and ask their developers to update their plugin/theme. There is no known bug in WP Core regarding widgets, just that some plugins/themes are incompatible.

What about the theme? Themes usually add custom widgets. Did you switch to a default theme? I am asking because I cannot replicate the issue with

– TwentyTwentyOne + Advanced Editor Tools (previously TinyMCE Advanced)
– TwentyTwentyOne + Advanced iFrame

And I stopped there. Please try to use a default (for eg. TwentyTwentyOne) theme and see if that notice is still there.

If yes, you could start a new topic in each plugin’s forum and ask the developers about this. For example, this one is for Advanced iFrame: https://www.ads-software.com/support/plugin/advanced-iframe/

Hi?@vladytimy,?

The result is just the same using themes 2017, 2020 and 2021 so I’m assuming that it’s not a theme issue.

I shall follow up your suggestion and leave comments on the respective forums. In the mean time I shall use the Classis Widget editor.

Thank you for your support.

Regards
