How can I undo changes in edited website code?

[sugarfootflower]

Hello

I tried to edit code on one of my website pages but unfortunately, I accidentally removed a part of the code. This in turn removed some of the text on the page. Is there a way to undo this change? I've had a look in the "Edit code" section however can't find a liquid file that relates to the page I edited: https://sugarfootflowers.com.au/pages/about.

Any help would be very much appreciated.

Thanks

Go over to your code page for your theme.

expand every folder and look for a dot next to the file

Open the file.

There's a drop-down menu that lets you open a previous version of that file

Save the previous file over your current (broken) file.

If you'd like further assistance, please message me.  

Thank you.

I made one code adjustment and that was for mobile pic sizes.  I've put it back to original and removed that code but it's still not working.
