I have just remade a fresh example of Roster 1.7.3 and installed the addons I use - here is the problem. I installed Siggen 0.2.4 too, but when I click "Siggen Config" button I get this:

Fatal Error
GD Functions are not available
SigGen REQUIRES GD with FreeType support

The "More Info" gives me this info:
Roster Diag
Logged in:[Logout]

Realm Status GD image mode enabled (rs_mode = on) in Config but FreeType support was not found.
Either load the Freetype extension in PHP or set (rs_mode = off) in Roster Config
MOTD GD image mode enabled (motd_display_mode = on) in Config but FreeType support was not found.
Either load the Freetype extension in PHP or set (motd_display_mode = off) in Roster Config

Someone knows what I can do? Or what I did wrong?

Missdwarf

GD isn't enabled on your server
If this is a personal server, you need to edit php.ini to enable GD
If this is a webhost (not a personal server) then you must ask them to enable GD, and hopefully, they will

TY for your quick responce. I will try contact hoster.

Hoster has now enabled GD at the server and it still aint working. About Freetype he says, that the security will be broken if he adds that, and that I have to edit it myself. But how?
Really would love to have the Siggen up working again.

SigGen will not work without freetype
There is no way around that, sorry

Do they give a reason why security is broken if it is enabled?
I know that many, many major web hosts that have freetype enabled any they are just fine

The hoster says, that he added Freetype support and Imagemagic (my mistake I said he didnt).
When I then showed him the Fatal Error he replied, that it will be to huge risk to ruin something in the controlpanel, and that I have to do it myself in config file.. ehm.. :-|
