Please uncomment your code back to the default.
In Portal Management
1. Under Content> Content Snippets > search for "logo" and pick the right logo URL. Example below for your kind reference

2. Change the value to empty. Make sure you are editing the right content snippet for your website. The easy way to identify is to filter by website. Highlighted again for your kind reference

3. Hit save and close.
PS: You may see the logo in the editor but if you sync and preview the logo will go away for sure.
