ISPConfig is a useful application,but it is not a version for Thai language. If anyone isn't already working on ,I can do.
You can get the language files from your ISPConfig instalation or from the installer tar.gz file bundle. If you want to translate e.g. from english to Thai , you can find the language files as follows: run this command on your server: locate en.lng This will result in a list of files in subdirectories of /home/admispconfig. Make a copy of each of these files named "th.lng". (Is "th" the correct ISO code for Thai??) Then translate the sentences in the files, but only the part on the right side of the "=" enclosed in quotes. In the file /home/admispconfig/ispconfig/lib/config.inc.php you can change the charset for the HTML headers of the pages.
