Reply To: Updated to last version and can't open admin page

Hi,
I revised the files, and now they are ok.
Now I have another problem.
My wordpress site a white page.
In the log file I found this:
[25-Jan-2018 11:59:54 UTC] PHP Fatal error: Call to undefined function vc_build_loop_query() in /home/aseisman/public_html/wp-content/themes/basel/inc/shortcodes.php on line 2817
This happened since I update the theme.
