Can't upload logo image or favicon image in 2.3.0. Gives no error just spins and does nothing

[wiliam_hughes]

My client, who is using Magento 2.3.0, cannot upload a logo image or favicon image.  It acts like its uploading but then it stops, no error, no upload.  I had the web host look at the issue and they said it was an issue found here. 

https://github.com/magento/magento2/issues/18688

Where can I get this patch to fix the issue?  From Github?

Thank you,

Bill

@wiliam_hughes I have not tested this but believe the fix you need is here if you wish to manually apply it. Else it should be included in version 2.3.1.

You just need to change two elements in a single file and then run:

php bin/magento cache:flush
php bin/magento setup:di:compile

You can also create an official Magento patch file to apply this if you follow the following guide else your only option is to look at upgrading to v2.3.1.
