Please check attachment. I have a fresh Magento 2.3.0 installation. Unable to upload a logo.

The error says "A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later."

Consol error

JQMIGRATE: deferred.pipe() is deprecated at /adminhtml/Magento/backend/en_US/jquery/jquery-migrate.jsjquery-migrate.js:45

enter image description here


I think it is bug in Magento 2.3.0 because when you try same with product water mark image, it is not getting uploaded and thats why it is not showing old uploaded image there.


In vendor/magento/module-theme/view/adminhtml/ui_component/design_config_form.xml file change fileUploader to imageUploader on line number 57 and 154

  • Yes. All image upload except Magento product. This happened. – Pratik Kamani Dec 10 '18 at 7:34
