Good morning, I need to migrate some custom modules developed in the very old version 1.9 to the current 23.1 . I fixed all PHP 5.6 statements that are no longer compatible with version 8.1 . Where required I added the settings in the global variables. I have 2 problems, some modules, once installed, have the following error:
Call to a member function read() on null (0)
specifically, the code there is $this->tmpl->read($index); , which is instantiated with $this->tmpl = CreateObject(‘etemplate.etemplate’);
the second error that occurs, in other modules, is as follows:
Call to undefined function create_select_box() (0)
How can I resolve these errors ?
Thank you.
