If I add SP simple portfolio and select a category it doesn't display my subcategories (even gives an error if the main category doesn't have any specific items: "You Have An Error In Your SQL Syntax; Check The Manual That Corresponds To Your MariaDB Server Version For The Right Syntax To Use Near ') ORDER BY Id ASC' At Line 3"

Is there a way to include the subcategories?
When you select all categories it does include the subcategories.
If there is no way to include the subcategories I will work around it with using multiple main categories. However I would have to duplicate some items in SP simple portfolio component to make them appear where needed. In which case a 'copy' item or 'save as' item button would come in very useful ;-) (also comes in handy when translating SP simple portfolio items to different languages)
Thank you in advance for your support.
