Is there really no one else who can help me with this important issue?
After a fresh install of WP 3.6 the problem disappeared. This means that the upgrading of WP created the problems.
Google and search for “widget drag and drop not working after upgrade wordpress”; a recurrent problem(!).
This is most likely because of a javascript interference.
When the javascript begins breaking (sliding tabs, dragging widgets, etc.), it’s typically because of a mis-coded plugin or theme.
So, the first step is to deactivate ALL plugins. Manually clear your browser cache. And try again.
If it still does not work.. do the same with your theme. Switch to the default WP theme. Manually clear your browser cache. And try again.
As you have already seen, it works on a new install of WP. So, the issue is obviously somewhere in one of your plugins or your theme.
Lastly, if none of the above work… you may need to add the following line to your wp-config.php file:
define( 'CONCATENATE_SCRIPTS', false );
Hello Josh,
Thank you for your reply!
I’ve upgraded WP from (I guess) 3.5.6 to 3.6.
I’ve de-activated all plugins, themes, cleared cache and activated WP-default theme 23. So only the WP-theme was active and no plugins and custom themes. But the problem was still there 🙁
This means that the plugins and or the themes weren’t the problem.
I’ve created a test site with fresh install of WP 3.6, my custom theme and some plugins and the problem was gone. So my conclusion was that the upgrade created the problem. I’ve searched Google over widget problems after upgrading WP. > Recurrent problem.
So my last resort for my client’s site would be adding define( ‘CONCATENATE_SCRIPTS’, false );
Thx again for your help!
No worries.
That is strange.
Did you set up the second site with the same hosting provider as the site experiencing the issue?
Hello Josh,
Yes, I’ve installed the second site with the same provider.
And just added “define( ‘CONCATENATE_SCRIPTS’, false );”
just above ” /* That’s all, stop editing! Happy blogging. */ “ but…. unfortunately not working. 🙁
Are you suggesting a provider’s problem, if so what exactly?
Thx again!
What browser are you using?
Have you tried using a different browser, or even from a different computer?
I’m using FireFox, Chrome, SeaMonkey and Safari. Same problem.
And On Windows 7 and Apple OSX.
The fresh install worked fine (!) regardless browsers or operating systems.
Perhaps going back and doing a manual update will help?
1. Download a fresh copy of WP 3.6.
2. Using either FTP or your hosts cPanel, we are going to manually copy over the files.
DO NOT copy anything to the wp-content directory. Leave that alone, or you may lose personal content.
Overwrite the files in the root, and the wp-admin and wp-includes directories.
This will ensure all files were updated properly. Maybe the auto-update process had a “hiccup”.
Hi Josh,
The auto-update might indeed be the main culprit. I’ve read postings that the problem might be related to compressing of javascript or php or something like that. And the auto-update problems appears to be a recurrent phenomenon since a few years(!). WordPress must come with a solution. I guess they are either ignorant or sleeping at WordPress 🙂
