Pending Dont show Viewer with php

[JoaquoCL]

TeaSpeak Server Version: 1.2.10-beta
O.S: Centos 7 x64

Im using php framework modified (i change the protocol "TS3" to "T").

When i put:
echo $ts3_VirtualServer->getViewer(new TeamSpeak3_Viewer_Html("images/viewericons/", "images/countryflags/", ""));

The viewer works but without icons, show the connected people, the channels, sub-channels, etc.

And when i put
echo $ts3_VirtualServer->getViewer(new TeamSpeak3_Viewer_Html("images/viewericons/", "images/countryflags/", "data:image"));

The viewer dont works and i have this logs in error_log:

PHP Fatal error: Uncaught exception 'TeamSpeak3_Adapter_FileTransfer_Exception' with message 'invalid file transfer key format' in /home/TeamSpeak3/Adapter/FileTransfer.php:75
Stack trace:

#6 {main}

P.D: if i put echo $ts3_VirtualServer->getViewer(new TeamSpeak3_Viewer_Html("images/viewericons/", "images/countryflags/", "data:image")); and i dont have connected people, the viewer works, but without icons.

My PHP Version is: PHP 5.4.16 (cli) (built: Apr 12 2018 19:02:01)

Hey,
It seems like the viewer require a specific file transfare port.
Take a look at line 136 /home/TeamSpeak3/Adapter/FileTransfer.php.
And remove the check there
