Hi,

I think I found the error. I will test it tomorrow.

Hauke · Joined: 02 Mar 2003 Posts: 1072

Hi,

it seems that some parts of the script are not generated. As a result, the if statement is not closed properly, which leads to an error.

I will investigate the problem futher and publish a solution, when it is ready.

Hi,

it seems to be a bit more complicated than I thought before...

Please try these changes on your m23 server and post success or failure with integrating another computer.

There are 4 pieces of code that have to be changed.

Please use the following patch file (

Hi,

an update is available via the m23 webinterface and vi APT.
