When you create a website, it error.
Error: Please allow extension : json

2. Go to PHP Selector | extensions feature (If this feature doesn't available on your cPanel account, please ask your hosting provider to enable this function)
3. Select "json" extension
4. Go back to RVsitebuilder 7 to create site again.
