Sunshine cannot be your front page
In order to have effective theme integration with WordPress, Sunshine Photo Cart makes use of WordPress’ endpoint rewrite API. What this does is take the URL of your Client Galleries page (exmaple: www.yourdomain.com/client-galleries) and then adds on the information about which gallery you are on (example: www.yourdomain.com/client-galleries/gallery/smith-wedding). So what Sunshine is actually doing is loading your Client Galleries page then replacing the content area with the Smith Wedding content and images.
The down side to using endpoints is Sunshine cannot be used as the front page of your WordPress installation. This is because WordPress needs to have the “client-galleries” part (or whatever you have customized this to be for your install) as part of the URL. This is a known issue with WordPress and hopefully we can get them to fix it eventually.
However, this can be resolved using a little redirection:
Install the Page Links To plugin
Go to Pages > Add New and create a new page called “Home”
Go to Settings > Permalinks and save settings, nothing needs to be changed (this just resets the URL settings for WordPress)
