Hello, I tried to import a demo (Enfold Health) but pages were not well charged, the result was bad so I decided to build my site without demo. The problem is that probally there are some settings of the demo I can’t delete. I tried to begin to build my site but when I try to buid a page using Avia a long written appears and it is also published on the site:
Warning: include(/home/customer/www/barbaram23.sg-host.com/public_html/wp-content/uploads/avia_fonts/lifestyles/charmap.php): failed to open stream: No such file or directory in /home/customer/www/barbaram23.sg-host.com/public_html/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/class-font-manager.php on line 477
Warning: include(): Failed opening ‘/home/customer/www/barbaram23.sg-host.com/public_html/wp-content/uploads/avia_fonts/lifestyles/charmap.php’ for inclusion (include_path=’.:/usr/local/php74/pear’) in /home/customer/www/barbaram23.sg-host.com/public_html/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/class-font-manager.php on line 477

and I don’t know how to delete this because this written appears on all pages, everytime I open the editor Avia.
So: how is it possible to delete it? How is it possible to delete all settings of the demo Enfold Health and to start from scratch?
I let you my credentials to log in my site, can you help me? I am not an expert… Thank you!
