If I put “https://amazon” it works

If I put “https://amazon.” (adding the “.”) I get 403

“Do you know if it is possible to, for example, add a link to the WP links database? Or but a URL into a post?”

not sure what you mean by that?

If I change the URL to a random text string (ie. “123”) it works fine

I also tried putting in a random image URL (ie. google logo) and I get the same 403 error

so something related to adding images

I don’t have any other plugins activated

Other ideas?

Thanks for the prompt response.

I use hostgator.com

It says: Virtuozzo on Linux CentOS 5.
