Site Down -0 - Using $this when not in object context

[english]

Hi,

I was taking a look at my site but it's down. The URL is www.softenglish.exofire.net I have a parked domain www.softenglish.cl. I get the error message 0 - Using $this when not in object context and the screenshoot I have attached below. Please help.

Thanks in advance.

I changed the Current PHP version: back to 7.0 and it's up again. Why is this so? Joomla recommends to change to PHP version 7.1. Any info will be appreciated.

Thanks
