The error message indicates that the logo’s aspect ratio must be between 100:1 and 1:100. This means the width-to-height ratio must fall within that range. To fix it:
Check the aspect ratio of your logo using an image editor.
Adjust the width or height to fit within the required ratio range.
Save and re-upload the logo.
Make sure the ratio (width/height or height/width) falls between 100:1 and 1:100, meaning it should not be extremely wide or tall compared to the other dimension.
If you have other questions, I will also answer them.
