New Version Error


I have the old version 2X and wanted to start to upgrade the new version I created a new folde and uploaded the files. I get an error Can anyone help Thanks.

Warning: Unexpected character in input: '' (ASCII=92) state=1 in /home/XX/public_html/new415/index.php on line 26

Parse error: syntax error, unexpected T_STRING, expecting T_VARIABLE in /home/XX/public_html/new415/index.php on line 26

Would have to look but you might want to check those files for malware intrusion…
