We recently upgraded WP to 4.9.2 with PHP 5.6. The site works fine. However, when we upgrade PHP to 7, the site threw HTTP 500 error. Any idea on how to fix this issue?
Thanks in advance.

It's definitely not the WordPress version that's causing your problem. It's one of your plugins or your theme.
If you're on cPanel hosting, look for the file error_log. The last error should give you an idea of what is causing the problem. You can post here if you're not sure how to interpret it.
