Blank page "PDA/Smartphone"

[Bienio]

Hi,
I install ocs agent on my android phone and send inventory to server. My phone is visible in administrator console, but when I click at “PDA/Smartphone” icon, there no data – only blank page (see screenshot). Agent collect and sent information about SIM and IMEI to the server - in exported XML file, that information is available. In ssl_error_log I found that:

Server version: 2.1.2
Agent version: 2.1.5

I hope somebody will fix this ;). Thanks in advance.
