Are you using the [cloud] shortcode to display the users files?
From the WordPress admin page go to Cloud > System and make sure there are no errors displayed at the top of the page. Specifically, we want to make sure that the the WordPress usergroup has read/write access to the /cloud/ directory. I believe the default permission levels for that folder should be automatically set to 775 by the plugin upon creation, but assuming your using Linux and you have access to the servers back-end open up a terminal and type…
‘ sudo chmod 775 /var/www/html/cloud ‘
If you want to give users the ability to use the back-end of the Cloud (from the WordPress admin panel) you COULD use a plugin like User Role Editor to give subscribers the ability to manage_options…. HOWEVER, that is a very bad idea.
I think what you want to do is a button to break the cloud out into it’s own window…….
<script type="text/javascript">
// Cloud Window Launch Code
function newPopup(url) {
popupWindow = window.open(
url,'popUpWindow','height=700,width=600,left=25,top=25,resizable=yes,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes')
}
</script>
<a href="JavaScript:newPopup('https://www.yoursite.com/cloud/');"><div style="text-align: center"><img src="https://www.youtsite.con/wp-content/uploads/2015/03/your_chosen_logo.png" border="0"/></div></a>
Something like this will work, but not all browsers will comply with the ‘ toolbar=no ‘ portion, and it’s much less than convenient for mobile users (as it will open a new window). To solve this I would add a landing page between your login page and your Cloud that automatically redirects users based on screen size to different pages that you’ve pre-formatted for mobile and desktop environments.
Cheers! Hopefully I didn’t screw anything up or waste your time. ??
