I've uploaded the file, 3C01.htm on your server, and during the installation there are 3 lines of errors displayed, but as it is too quick, I just skipped the details.
The exercise worked just fine on your server.
I hope it's simply related to my language file but I can't figure out where the problem is. So, I included some files here and I hope you will have time looking into it. Thanks in advance.
- File 1: from mod/hotpot/attempt.php (I guess this may cause problem)
- File 2: from lang/en_utf8/hotpot.php (this works ok)
- File 3: from lang/zh_cn_utf8/hotpot.php (this also works ok)
- File 4: from lang/zh_tw_utf8/hotpot.php (I also guess this might be one of the problem files).
