I am getting these errors daily and wondering if anyone else was or if there is a fix.

This is on paleadershipconference.org/.com. Running the Joomla Fest Theme.

Checked my php settings with your link and all recommended items are off.

So probably one of your extensions overwrite this rules, please try to add to your template ini_set rule like it is described here Quickstart Installation Problems – How to fix them?
