Mi JOOMLA se satura a menudo

Estoy usando un Joomla a versión 1.5.23 . Esta es una versión de Joomla que se liberó en 2011, hace ya 15 años. Los mensajes de aviso que están llenando el error_log de mi web corresponden a características del mismo que están obsoletas; te pongo un fragmento del fichero de error, pero el mismo se está llenando rápidamente con mensajes como estos:
