Adding customer issues

Sorry,

I got it.  I hand inadvertently deactivated the default inventory location.  Hard to ship to if you can't ship from.

Like I tell my wife,  I'm an idiot... but it's okay, I'm GOOD AT IT!!!

can you please explain in details how you solved your issue.  cause i am having the same problem.
Inventory is active.

I'm not using a sample data but i am setting up a new company.

Thank you

I got this error while creating new contact , my TB_PREF is 10_ and working fine with TB_PREF 0_, the combobox of Contact active for: is empty of You have to select at least one category.

error log showing this: [23-Nov-2021 19:33:12] 0:Ammar:simple_crud_class.inc:114: key() expects parameter 1 to be array, string given
when I commented this code in contacts_view.inc

//crm_category_types_list_row(_("Contact active for:"), 'assgn', @$this->data['contacts'],
        //    array('subclass' => @$this->subclass,
        //        'class' => @$this->class, 
        //        'multi' =>true)
        //        );

then it is saving the contact details in database but not showing on contacts

Thank you for wishing me Good Luck, how can I migrate to latest version with all the data I have
