Dropdown Menus mot working in latest Wordpress 5.6

keynet

There's a problem with dropdown menus in Wordpress 5.6 caused by out of date JQuery syntax in Vertex supplied with "Design Control" theme and probably others. The first menu drops, then no further menus work until the page is reloaded.
A temp workaround is to use the JQuery migrate helper, and enable old JQuery but Wordpress version of Vertex needs an update as this is only a temp fix.
The migrate helper log says:

/wp-content/themes/s5_design_control/js/core/s5_flex_menu-min.js
jQuery.fn.size() is deprecated; use the .length property

I tried manually changing this as suggested in both the minimized and JS files, but that's not enough to fix it in my testing at least

Please would you look at a Vertex update before they kill the migrate helper in next WP release (March/April ?)
Thanks

Hi keynet,
The Slideshow and Menu won't work on the WP 5.6. However, I have found a solution for you, you can install the following plugin to migrate the Wordpress JS.
Enable jQuery Migrate Helper

Yes that's a temp fix as I said - as I describe above - but a permanent fix is needed, probably for ALL s5 themes (all menus affected) as they plan to discontinue the helper / old JQuery next version of WP. https://make.wordpress.org/support/2020/12/handling-potential-jquery-issues-in-wordpress-5-6/

Any update on this ? Wordpress 5.7 comes out in 3 weeks time, and it seems all Shape5 sites using the old JQuery library will stop working then. See

Hi keynet,

Yes, we will check it.

I think the theme will work fine with the WP 5.7 when installing the Enable jQuery Migrate Helper plugin.
