Warning upon Install

I get this on the Sermons page:
Warning: Creating default object from empty value in /home/admingcc/public_html/components/com_sermonspeaker/views/speaker/view.html.php on line 66

In the backend when adding a sermon, I get five of these:
JFolder::files: Path is not a folder
followed by lots and lots of lines like these:

First of all, this are only warnings. Which means the code "should" still work. You can disable this warnings in the global Joomla configuration. Set the error reporting to "None" for production sites.

You posted this in the "SermonSpeaker 3.x" forum. Are you really still using SermonSpeaker 3.x? You really (and I mean REALLY!) should update to Joomla 3.5 and SermonSpeaker 5.5.
Have a look at the FAQ to see which steps to take: www.sermonspeaker.net/faq/27-how-do-i-mi...rmonspeaker-4-x.html

Thanks for the quick response. I changed error reporting to none and am still receiving the warnings. The extension is working properly but I need to remove these warning messages from the frontend.

I don't have the time to do the Joomla upgrades on all of my small sites that are still working properly. Thanks for the advice.

If you still get those warnings even if you have error reporting disabled, then something is very strange with your server.

Unfortunately, I can't provide you more support with this. Both your Joomla and SermonSpeaker version are outdated by years. My only advise is to upgrade asap. There are no excuses for not doing it.
