php - Can't make SimplePie Laravel bundle to work -

I am trying to use SimpleP for Laravel to parse RSS feeds. I have followed the instructions and all, but it does not seem to work.

This is my view of RSS

    
 and this error appears:  
 
 The non-static method SimplePie_Misc :: fix_protocol () should not be called statically, it is incompatible reference Should handle $$  
 C: \ wamp \ www \ ctnpepo \ bundles \ rssparser \ libraries \ simplepie \ SimplePie.php line 834   
 The way?   
 
 
 It is only in an inherent simplicity, and you can safely ignore it.
