Lightroom classic not saving my edits

I have the same issue after update of LRClassic to version 12.0
I have lost all my edits.....
Any tip on how to restore this??

LR Classic Never Asks if you want to Backup your Changes as the original file is never changed.

It does ask if you want to Back Up the Catalog file, the Database file LR uses.

By Default LR is set to backup the catalog file once a week. So if it hasn't been at least 1 week since the last time you backed up the catalog file that dialog box will not come up.

In all honesty you need to learn how LR works and how to properly work with LR.

You can do that by viewing some of the good online tutorials on the Adobe website for using LR Classic, they are free.

"I had to reinstall due to a computer problem. When I closed lightroom it would ask if I wanted to back up my changes. That doesnt come up now, and my edits aren't being saved."

Don't worry. Your edits are safe (and saved). This dialog is for making a backup copy of your catalog, not for saving the edits. The catalog contains the edits and the edits are automatically written into the catalog. It's a good idea to make regular backups of the catalog, but it does not mean that edits are not saved if you don't do that each time.

Check your Catalog Settings  [Ctrl+Alt+comma]

And when you do see the Backup dialog- be certain it is making the backup zip file to another physical hard drive!

Explain what you mean "my edits are not being saved".

While you are working in Lightroom all the work you do is being recorded and saved to the Lightroom Catalog file. This happens real time there is no save function. If you close Lightroom and reopen at a later time you should see the work and edits to your images.

If you mean that when you view in other applications you do not see the effects of your edits, then this is as designed other applications cannot read info from from your Lightroom Catalogfile. However there are options in Lightroom that allow you to write the info to the file for sharing with other applications.
