There are many browser security issues that can affect the functionality of the Chargify Hosted Pages when placed inside an iframe on your site.
We cannot provide support for issues that arise from the use of hosted pages inside an iframe.
Chargify hosted pages must be able to set a cookie in the client’s browser in order to work properly. In some browsers, if our page is embedded inside an iframe, our cookies appear as “3rd party” cookies and are often blocked by the browser. We have implemented technical workarounds, such as setting the P3P headers as required by Internet Explorer for 3rd party data. However, since the browser security landscape is always evolving, we cannot guarantee that our pages inside an iframe will work consistently.
If you choose to use our hosted pages inside of an iframe, you assume the technical risks associated therein.
Currently, the only way to remove the Company name from the Public Signup Pages is to upload a custom logo for each site. This will replace the company name with whatever the logo shows, which you can make acme1.com, etc.
