I am working on importing my existing content and categories into K2 but get an error message when I use the import function. Can anyone help me out?

This is the error line:
public_html/administrator/components/com_k2/tables/k2category.php on line 102

Hi. It would be more helpful if you post the error along with file. Anyway, you can go to K2->Information and check that your system meets all the requirements.
