Problem With 4.2.3 version

[ramesh_umk3]

Suddenly my forum is down today when i checked log i see below error

Parse error: syntax error, unexpected '<' in /home/xxxxxx/public_html/includes/class_core.php(4719) : eval()'d code(1) : eval()'d code on line 3

1) i disabled all plugins via config
2) uploaded all files and upgraded again

what ever i do i still see same error .. Anything else i have to do ?

thanks
