_I don't understand the deep inner-workings of Weebly's servers or programming, but every once in a while, things just stop functioning.
Before getting clicky and frustrated, close out and re-enter the weebly editor via the blue ENTER button.
If just closing out doesn't help, close out, log out, and log back in.
Usually, that solves the problem without making things worse by . . .
_Not exactly. You can't download an archive of the site to your computer, but GoDaddy does back up your site when you first publish it, for later versions if you select that feature when you are publishing a change to the site online, or when you select MANAGE>BACKUP/RESTORE, enter a name for the backup and click SAVE WEBSITE. (Do back it up!) Make a backup of your existing, even messed-up site before restoring, just in case.
Complete restore: if you have a disaster, GoDaddy lets you restore your site completely from one of up to five backups, however there is no way to select just one page or block to restore using this function.
Partial restore: this workaround is especially helpful if you've messed up just one block (or just a few) while doing major changes to your site, but it needs to be done carefully . . ..
_Weebly is not great with the undos. I think it's their automatic save that is the culprit here. Usually that auto save is a very good thing — otherwise we'd be saving each little step in each little section, which could be positively crazy-fying.
Text: In the case of text, as long as you don't navigate out of the text section you are working in, you can often still press COMMAND-Z (Mac) or CONTROL-Z (PC) on your keyboard to undo what you've just done, just as if you were in a word processing program. But navigate that cursor out, and it's saved as-is.
Deletes: In the case of deleting something you want back, that's where the "not great" comes in. It's deleted.
The first thing I had to learn with Weebly was to slow down and try to be very present and zen-like, so I did less un-undo-able things. The other thing I learned was . . .
