 * I get a warning: Undefined array key 6 in /www/doc/ on line 78
   The issue disappears
   when I switch the WP language in settings to english. But I need the page in 
   a differnt language. The number on array key differs based on how many tabs I
   have in my block. Is there a way to solve this?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fundefined-array-key-58%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I took a look at your site and saw that there seems to be a little mix-up with
   the amount of content compared to the tabs. That’s likely what’s causing the 
   error. Try to recreate this tab in another page and see it this error comes on
   that page. Make sure you add tabs properly, sometimes it happens while we do 
   undo CTRL + Z. Let me know if you need anything.
