** Why the error happens?
For those using our templates, after having done installing templates, you often unpublish all menu items, and start to add new portfolio articles from scratch. Because there is no active menu item viewing with TZ Portfolio+ available, portfolio articles can't be shown out normally in front-end and the URLs are completely wrong.
For some specific templates:
Autoshowroom - Car Dealership Joomla Template: you might encounter this error "0 - call to a member function get() on null" (Image 1)
Charity - Nonprofit Joomla Template: when you try to open a portfolio article, it doesn't redirect to detail page, and the url may display like http://localhost/charity_1.6/index.php/component/tz_portfolio_plus/article/5-events/christmas-charity-giveaway/29?Itemid=101 (image 2)
- Create a hidden menu viewing to TZ Portfolio+
Step 1: Create a hidden menu
Step 2: Add a new menu item in hidden menu
Please add new menu item and assign it to hidden menu
Menu item type: Select TZ Portfolio Plus > Portfolio
Choose portfolio categories and template style
