Can't use array as an reference SnortSnarf HTMLMemStorage
I'm trying to install SnortSnarf and I'm getting the following error on Ubuntu, next to the terminal is the HTMLMemStorage.pm file. 
I've tried playing around with Line 290 but none of it worked and there doesn't seem to be any solutions I could find online about this. I've tried https://www.linuxquestions.org/questions/linux-security-4/snortsnard-generation-problem-111708/ and CGI error Can't use an array as a reference but it's not deprecated so I'm not sure how to go from here.
Solution
The left-hand side of -> must be an expression that returns a reference.
