Images in multisite don't have http:

Hey Vahid,

Having no “http:” in the image source makes the protocol relative and shouldn’t cause any issues. It’s similar to using the relative URL.

The absolute path = https://etuts.ir/wp-content/uploads/2015/10/site-logo.png
> can be used anywhere and will try to use the http protocol.

relative protocol = //etuts.ir/wp-content/uploads/2015/10/site-logo.png
> can be used anywhere and will use the default protocol at the domain etuts.ir (e.g. https or http)

relative URL = /wp-content/uploads/2015/10/site-logo.png
> can only be used on the same domain where site-logo.png can be found.

I’m not sure why you do not see the image on your site, but I do see it here, centered above the header image.

I hope that helps.
GL with it!

Thanks yes you’re right.
but the problem is that images aren’t loaded in the website! I mean I can see this image
//etuts.ir/wp-content/uploads/2015/10/site-logo.png

but it’s not loaded in design.etuts.ir
it’s just loaded in etuts.ir

what should I do about that?

The error there is “403 forbidden”.
You probably need to change the file permissions (CHMOD) to 644.
If 644 isn’t working, try 775.

You can do that through FTP, e.g. FileZilla — Tutorial.

Sorry but permission of which files?

Ah, sorry I didn’t mention… I thought about the images, but you might want to verify the chmod of the folder as well.

• The folder should have chmod 755. If that doesn’t work out try 775.
• The images should have 644. If that doesn’t work out, try 664. (I doubt 775 would be necessary)
