I created a site with WordPress Betheme, and everything was perfect before, but this morning I found out the BeTheme menu is disappearing in the dashboard, I can find it in Appearance > theme, as showing below in pic. And there's nothing in page editing, no builder, no section, etc. I don't know why, please give me some hints on how to solve the problem, many thanks!

Here is an instruction on how to update the theme:
http://themes.muffingroup.com/betheme/documentation/#general
Theme updates will not delete your content unless you have changed the
files directly in which case we suggest using a child theme.
We also recommend creating a backup file.
Please remove the theme completely from your theme folder and install a
fresh copy. Do not overwrite files.
