As I said before there is only one solution to this problem. It sounds like you have done “Publish” but not “Re-Publish All Files”
They are different and the difference in very important.
Only Re-Publish All Files will ensure that all resources are re-published, otherwise RapidWeaver will skip over the things it thinks have already been published.
I’m still quite optimistic that this single command, done just once, will solve the problem. It takes a while to finish – but once done I think everything should be in the right place with the right permissions. But do remember to clear your cache or visit the pages with a different browser to make sure that you’re really seeing the changes and not just the cached copy on your own computer.
In the unlikely event this doesn’t fix the problem, then we have to dig a bit deeper and gather some more information about the web-server.
If the files truly are in the right place and have the right permissions – yet the web server is not serving them then the only way forward is to check the web-server logs to find out why the images aren’t being served. This will likely involve reading the FAQs for your hosting company to determine how to find those logs or contacting your hosting company to ask for help with that.
But I would not contact them until you were 100% sure that the site has been uploaded with:
Re-Publish All Files
So try that first, then check back here and post a URL to a page that has problems. If that really doesn’t solve it – we can help you gather information (screenshots of the host files in place would be a good place to start) to take the next step.
