I have a client who is trying to inject some JS directly into a post using the web interface. The script is stripped out on the live site.
I am unable to replicate this behavior on a local installation. The JS is added as expected.
The main difference between my installation and the client's is that my installation is a fresh WP3 installation, whereas the client's is WP3 upgraded from WP2.
Is this a configuration option or a legacy issue? Is there some other reason why this might be happening?
