I added your WP Socializer addon and I think it’s awesome compared to all others I tried. While setting it up, I had to add a custom icon for Minds.com and while doing so everything was fine but when it came time for the icon, I decided to search for it on google and pasted the link to the icon. It looks great on the website, but while scrolling I realized that the icon is not with a transparent background. So at this point I went to edit and change the image, only to keep getting this message shown in the screenshot.
I have tried looking for the code with an editor for addons, removed the extension and added it back but it doesn’t seem to work.
Can you please tell me how I can rectify my error.
