When you see the message below:
Parse error: syntax error, unexpected ‘{‘ in public_html/wp-content/themes/wp_glory/framework/extension/extendvc/vc_includes/vc_functions.php on line 1
You should update the file:
public_html/wp-content/themes/wp_glory/framework/extension/extendvc/vc_includes/vc_functions.php
Download the theme from themeforest, find that file then upload and replace it to your host.
