Apache error (Undefined variable $data_temp)

I have just installed a brand new WordPress with the Festinger and Elementor Pro, Elementor, and Astra Pro plugins.
I have noticed an Apache error related to Festinger in my host’s administration and I hope this information will be useful to you.
Have a good day.

PS: What plugin was used to build this forum? I like it a lot.
