Hi,
The double slashes within the image URL may indicate that somethin is missing when parsing them, but I’m not sure.
I’ve logged in with the credentials, but I believe it does not have administrator rights, as I cannot see the ajax search pro option, nor some other ones. Can you please fix that? Can you please also provide temporary FTP access as well? I highly doubt this is a configuration issue, and it’s unfortunately working correctly on my multisite test environment.
