I am currently inside a Developer Sandbox within Salesforce. Inside the developer console I am able to create static resources of the MIME type text/CSS. I know this because they show up when I display static resources: Open Static Resources

However, whenever I attempt to load these static resources, it gives me this error: enter image description here

Normally, it appears for non-developer orgs, but I also get this following error window as well:

Which leads me to believe something more subtle is going on.


Regardless, how do I properly load a CSS static resource in a developer org?

  • under Setup > Company Information, what is the Organization Edition ? (just to confirm) where you are getting the api disables for this org message?

As mentioned in the edition features, or this kb article, professional édition orgs do not have API access enabled, hence the error
