Thanks for solution. I've fixed all layout by wp and abundance customer panel again, and it's took only one extra hour of work. Thanks for advice to do a backup file of database, it's necessary, and I'll do it. But i'm afraid that this "mistaken pushing" to this "special button" can repeat again because this button is so big, and it's have no question "Are you sure to do tis function" so, there's any kind of alert or secure... Let's think together to do something with this button. Have you some script to deactivate this button? Let's have a solution. Me, and i'm sure, no one of your other clients want to have a "design crash" at time of active working of site and online shop, and of course, to restore database form backup it's not a "beginner" option. I like abundance, so let's do some fixing to make me and other client all over the world to be happy and loyal clients.
P.S. i even like this line under the footer - "© права захищено - veganohooligano - Wordpress Theme by Kriesi.at", so give me a reason to proud of it!
Thanks a lot!
