Call to a member function get() on null error

Post by geoffp »

Hi Jan

New error since moving to Joomla 4 - now 4.4.4
Phoca Cart 4.0.10
pHp 8.1

An error has occurred.
0 Call to a member function get() on null

I see this in the Orders Section - when clicking on View Order, View Invoice or View Delivery Note icons
System is working overall however

What should I do?

Hi, first, enable debug mode to see whole error message including the trace to know from which part this error comes.

Hi,
1 () JROOT/plugins/content/mavikthumbnails/mavikthumbnails.php:126
At first you should disable the Mavikthumbnails Plugin for testing because it's an J3 plugin.
See: https://extensions.joomla.org/extension ... humbnails/
At second you should uninstall this Plugin if the error is gone due disableing.

Kind regards,
Benno

Brilliant - that kills the problem stone dead.

Will have to find an alternative for Mavikthumbnails

Thanks for your help
