Can't Save any Settings

I attach my Company logo

Edit my Currency Symbol (Changed it via phpmyadmin)

Click save - gear turning - Nothing

Also trying to add customer username for invoice login - Error saying Country needs to be set


Could you please post the output of the browser console here?
You can search on Google on how to open the console.

Be aware that the logo uploader does not work with all file types. At least it didn’t work with PNG files for me. When I converted my logo to JPG and uploaded it, it was working alright ( though it’s displayed distorted in the backend ( not on invoices or online though )
