It seems you have not correctly licensed Image Resizer: https://stackoverflow.com...mage-appears-red-dot
This happens if you enable a plugin that is not part of the "Essential Edition" https://imageresizing.net/plugins/editions/free

The Image Resizer feature has been implemented in Hotcakes for years and I've never heard of this happening before. I'm guessing you're also using another module that has installed a newer version of Image Resizer. The version that currently is included in Hotcakes is 3.4.2.
