Hello.

Your question is not clear. On what page your see "Not found" error?

[kitara]

Could you help me, that only happed in Admin Control Panel

usually it happens when you got some javascript error on page with grid.
Can you open developer tools in your browser (press F12 key) and open Console tab and try to replicate issue

Yes i think it has error in table render grid lines, and i dont know how to fix this, please tell what to do, below is code i got from windows where error appeared

<div data-growl="container" class="alert alert-danger" role="alert" data-growl-position="top-left" style="position: fixed; margin: 0px; z-index: 99999; display: inline-block; top: 20px;"><button type="button" class="close" data-growl="dismiss" style="display: inline-block; position: absolute; top: 5px; right: 10px; z-index: 99998;"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button><span data-growl="icon" class="fa fa-thumbs-down"></span><span data-growl="title"></span><span data-growl="message">&nbsp;&nbsp;
