I have a wordpress dev site in a sub-domain of the real site while it is being developed. My ssl cert is for the main domain.
I installed and activated wordpress https plugin in the dev site. The header graphic on the dev site disappeared. In Firebug I could see that the css is trying to load the header graphic as https. I see that's the problem.
After the site is developed I will promote it to the main domain so then https should work, but is there any workaround to be able to keep the plugin activated while under development in the subdomain and still display all the graphics normally?
