We are not using tooltips in any part of K2.

This is from another plugin. Make sure this code is rendering after Bootstrap or try to contact that extension's developer.

Thanks Krikor.

I went by trial and error and found the plugin causing the conflict.

Issue fixed.

You 're welcome Matthias,

Could you please post which plugin was causing this conflict so other users can benefit as well?

Thanks :)

Sure thing.

It was the Better Preview Plugin from NoNumbers that caused the conflict.

Thank you Matthias

Hi Krikor

I have had the same problem and I don't have any plugins from NoNumber.
My errors show up as:
Use of getAttributeNode() is deprecated. Use getAttribute() instead. mootools-core.js:108
TypeError: jQuery(...).SLScrollToTop is not a function index.php:115

This is when looking at my K2 Media Manager. However I first noticed this problem when earlier this week I tried to add an image to an item from the 'Browse Server' button and was shown the same type of white popup.

Concequently I have switched my System - Skyline Scroll To Top plugin (extstore.com) from jQuery to Mootools. Seems to have resolved the issue.

Any reason why this would affect only the K2 media manager and nothing else on the site?

Other aspects of the site might have been affected as well but the result might not be this visible.

Did the drag n' drop reordering work for example?

In general JS conflicts or errors can cause error even if they are not visible at once.

i have the same problem can you help

Hello I get a 404 error when I try to load the link you sent us.
Furthermore if you have not setup the SSL / https configuration properly this will lead to files not being loaded and several parts (including the media manager) of your site to stop functioning.

Any idea guys ?
