Download certificate for iOS/Android client Error

Question

When i try to download the Certificate on an iOS device nothing happens. The same behaviour vie User Portal and Admin interface. 
 When i use Dev Tools in Chrome i get this error when cliking the link: 
 
 Uncaught TypeError: jQuery.handleError is not a function at HTMLIFrameElement.downloadResponse (common_min.js:3333) at HTMLIFrameElement.dispatch (jQueryYUI.js:25) at HTMLIFrameElement.elemData.handle (jQueryYUI.js:25) 
 
 It is the same behavior for all these links: 
 
 Download for Windows 
 Download for MAC OS X 
 Download for Linux 32 
 Download for Linux 64 
 Download certificate for iOS/Android client 
 
 Any suggestions?

Sindrehal, 
 it seems that your CA is broken. Change one field of the Default CA and save it (or try to re-generate it using the gear icon). 
 Here another thread where a user had the same issue.
