One of the toolset plugins is causing a bug in the Post Edit screen. :
TypeError: this._setOptionDisabled is not a function jquery.fancytree.ui-deps.js:449:8
jQuery 22
initDialogs toolset-shortcode.js:537
init toolset-shortcode.js:1774
shortcodeManager toolset-shortcode.js:1919
<anonymous> toolset-shortcode.js:1924
jQuery 4
THis is happening across multiple sites with various plugin setups so it IS DEFINATEY a bug in the latest Toolset releases- I'm gusessing not liking a WordPress update. / js update
Ok. When i downgrade all of the Toolset plugins it still isnt working. Switching off ONLY the TOOLSET plugins means that it works. Swtiching them on again breaks the backend Edit screen with the error above.
I have isolated it to ONLY happening when the TOOLSET plugins are active.
This seems to have occured very recently. The issue is, why when even downgrading the versions, it still breaks? COuld it be that all of the plugins look for a common file which is in tern breaking things?
I have found the bug for you. Toolset is causing an issues with Jquery UI. Specifically the ui-button. Does this help you diagnose further??
When I dequeue this in the functions.php the backend Post Edit Screen works again. It gives other errors but at least we have functioning edit screens on all our websites now! Its only temporary so hoping you can give me a proper patch...
add_action('admin_enqueue_scripts', 'unload_all_jquery');
function unload_all_jquery() {
//wp_enqueue_script("jquery");
$jquery_ui = array(
"jquery-ui-button"
);
foreach($jquery_ui as $script){
wp_deregister_script($script);
}
}
I may have removed or commented it out. I went through each Jquery UI script until i isolated this being the one. However if you look back over my messages, toolset-shortcode.js seems to be the route cause or at least important in some way. Also this file or one of the dependancies its calling: jquery.fancytree.ui-deps.js:449:8
Hope you can get this bug patched soon as I'm sure many others will encounter the same issue when they update WordPress to the latest version!!
You have access to the website admin already - are you able to make a backup from there please?
The bug / problem is still unresolved and affecting ALL of our websites with Toolset installed (over 150 websites) so this is increasingly urgent as the patch I came up with is only temporary and not helpful as although it allows Post edits, it stops the Views / Types content templates from being editable.
I did make a backup and restored it onto my server.
However the issue isn't present there and on the functions.php file i'm not able to see the script that you used to de-queue the js file that is causing the issue.
Essentially on the copy the problem isn't there unless you made some changes to the toolset core files. I also tried logging in again but it seems your website is throwing an error 500 that is preventing me from accessing the login page.
