Hi.

I have noticed that when I add parameters in my URL (and also when a link from other website, like Facebook, insert parameters), my website give me the following error:
0 Using $this when not in object context

Look that:
www.cafecomfilme.com.br/criticas/critica-do-filme-bohemian-rhapsody?fbclid=IwAR1D3F9E6vZvQZrrBYcFMQq9rCUCeBOobHgvIFhsRC9aFz41vW15HD9riCE

The same page works fine if I remove the parameters from Facebook:
www.cafecomfilme.com.br/criticas/critica-do-filme-bohemian-rhapsody

Ok, I can remove the parameters manually, but my user won't have a clue what to do and will leave the website.

So, anyone have a hint to fix this?

Thanks in advance!

Best regards!

By the way, I'm using:
Joomla 3.8.12
K2 2.9
Modules from K2
K2 BNR
XT Link for K2
Gavick template

Just noticed that this error only happens in articles, in categories, the parameters works fine:
www.cafecomfilme.com.br/criticas?facebook
www.cafecomfilme.com.br/criticas

Is there something to do with a code in my override files?

Thanks again!

Ok, I guess I solved it.

I had this piece of code to avoid duplicate URLs in my website and also to collect only the original URL:
<?php
if ($this->item->link!= JRequest::getURI()) JApplication::redirect($this->item->link,'','' ,true);
?>

It was the first thing in my item.php. I just removed it and now parameters are working.

Well, if anyone has the same problem, there's the solution.
