After updating the single-product template, the product description suddenly disappeared.
Please help to check.
Please turn off all of the plugins, refresh your cache, and check if the problem persists.
Moreover, if you use a child theme, switch to parent and recheck it.
Also, ensure that you have the appropriate product template assigned.
I updated the single product template after adding Product tabs, but it disappeared when I refreshed the template page.
I followed all the methods you said, but the problem still exists.
Please send us the WordPress dashboard and FTP access privately through the contact form, which is on the right side at http://themeforest.net/user/muffingroup#contact, and we will check what might be the reason.

Sorry, but the login credentials you sent do not work.
The FTP does not work either. Please send another message and ensure that login credentials are correct.
I have again the same problem with the new user you created.
Did you check if the account is working properly?
Please try again.

Unfortunately still the same.
Also, please do not share credentials on the forum, as others can see them.
In a private message, you provided a link to another website, but I assume that is your staging domain.
However, I readded the tabs element to the single product template, and everything works fine.
Did you proceed with any extra steps when the problem occurred?
