The error is from a social script of Crea8Social that I uploaded to a website. I passed the script data to the site, and when I installed it I filled out the admin form and the database, the last one to give Save and install this appears to me:
Error Page:
Error occurred: Call to a member function fetch_assoc () on boolean on line 1015 in / home / vol3_6 / (data on my page) /htdocs/includes/core.php
Why is this happening? Is it possible to solve it?
