1) Make a backup
2) we Need to understand why it is so:
  1. disable all plugins
  2. go to default theme

Let's see whether all is well.
If everything will be OK, then enable one plugin at a time and test not spoiled all again
3) When you find the problematic plugin, then try to reinstall it, if not help, then contact the developer of the plugin

Apparently the styles of the plugin affect the page. Nonsense of course...
Semyon says is correct, you need to check the conflict of the plugins. And theme.
