Mambo not working after upgrade (Chopin)

[Audiolis]

Since last upgrade on Chopin my site shows a long message with lots of:
Deprecated: Assigning the return value of new by reference is deprecated...

At the end I get
Fatal error: Call to undefined method mosMenu::mosDBTable()

¿Can it be fixed or do I have to try to update Mambo or migrate to Joomla?
Thanks in advance

From my understanding, Mambo ceased development just over 3 years ago. The upgrades of the servers were to PHP 5.3.6.

You can add a line to stop the Deprecated messages (deprecated means it runs now, but may not on the next PHP upgrade). The Fatal Error would require a lot more work.

It may be time to migrate to Joomla or another CMS.
