This error affected Joomla 1.5 and 2.5, both of which reached end-of-life over a decade ago. The Parameter 2 to frontpage() warning was caused by deprecated PHP function signatures in legacy Joomla components. If your Joomla site shows this error, it is running a critically outdated version with known security vulnerabilities.
