Lost page after "Could not save block data"

[Elon Report]

Had a page that took a couple hours to perfect.   I tried to move a block, got the error above, and lost all data in that block!

Is there a way to get it back?

Edit:  Would this happen if two administrators had the block open in edit mode?

If 2 have had it open and one has saved it, then they may well have saved it with no data. There is no way in which to recover a block without restoring a backup from an earlier point in time

Tip: Create the block in the ACP as Pages block. That way, nothing you do on the front-end can kill it.

@Marc Stridgen He didn't actually want to edit the page, but because he was in the Administrators group, it opened when he visited the page.  Shouldn't the default be set to not edit the blocks when visiting?

I'm going to see now if there is any automated backup in this incredible software...

Its only set to open when you click on edit from the admin CP. It doesnt open that way when visited from the front end using a normal link. The reason it opens that way from the admin CP is that the intention of that button is to edit the page
