Link to a page where the issue can be seen: hidden link
This page was working well but something has happened, best illustrated in the screenshots.
I've tried deleting the view and page the view is displayed on and recreating. Using different names for the view and page.
One strange thing is the issue is different in different browsers.
Also the padding on the actual list isn't in line with the COMPOSERS heading. I've tried inspecting the code but I can't find where the padding is coming from.
It seems like something went wrong trying to create a chat, let me follow-up.
I logged in to your site and saw an issue on that page, more obvious in Firefox than in Chrome.
I also notice that your plugins are a few versions out of date. I can see in the markup a missing row class which was recently fixed, could you please update plugins and test again?
(You might want to make sure you have a current backup first.)
I spotted the empty class in the HTML output and guessed it was the reported issue, but looking at the View I see that you add the row with an empty class yourself.
See the screenshot where you can see an ever-nesting series of divs that contain the composer links.
