Hi Joomshaper Support Team
The following problem arose while I was using the Product search filter to check for a possible duplicate product name.
When filter option 'All' is chosen, the following message appears:
"An error has occurred.
0 Call to a member function setName() on null
"
After that the product list is unavailable until after logging out and back in to Joomla admin.
I have create a screen capture video for your reference.
