php error after clearing system cache

I am getting an error message after clearing the system cache.

The error message is : Notice: Undefined property: stdClass::$names in /home/rockharb/public_html/23550proof/components/com_sermonspeaker/views/series/tmpl/tiles.php on line 100

There is one of these errors for each series.

I am using the "tiles" layout. It was working and looking beautiful until I cleared the cache.
Site info:
Sermon Speaker 5.3.1
Joomla: 3.4.1
PHP Version: 5.3.29

Anyone have an Idea of what is going on?

PLease try the latest version of that layout. You can download it www.sermonspeaker.net/download/layout-tiles.html

I had that installed... I re-installed it just in case and am still getting the same error.

Ah I see the issue.
Can you try to change the "$item->names" on the mentioned line to "$item->speakers"? That should do the trick.

Also the same on the line below that one.
You can see the changes I had to made here. Maybe that helps:

Thank you! That fixed it.
