I can save for web 100% ( A value between 00 and 00 is required. closest value inserted.

I was just saving and working on the same file, same size, until just now.

At some point, I got this notification and couldn't save. I've heard that older versions of Photoshop had this error before.

I need to get work done and this is a very big problem. I've tried everything, but I can't solve it.

It's not even a large file and I don't know why this happened.

Please help me
