Thanks for the support.
Now I have deleted the March updates and installed old January updates fearing that the latest update might bring agin the fatal error. Is that Ok or should I update the theme to the latest version ?
Bluehost offers only 7.0 version of php. They do not have the php 7.2.0 version available for the public. Will this affect the website performance ?
Thanks again
Thanks for the suggestions
I understand the first step : Please remove this file via FTP
/themes/enfold/config-templatebuilder/avia-shortcodes/events_countdown.php
But I do not understand the second step :
it has moved to this file
/themes/enfold/config-templatebuilder/avia-shortcodes/events_countdown/events_countdown.php
Should I up load this file ? From where should I obtain the file ?
