Hello Tobias,
I am trying to make a smokeping in portugues and i have still problems with the accents(úéáõã) and also with Spaces in the names of files in the config file. Everytime i got a message like "cant find the table defintion" or something like that. I found only one short example how to display the html but even this don`t work because in the example was used a .htaccess file which i donŽt have. I think that is the same problem like with umlaute in german, so that you still have a solution and i only was not able to find it. Perhaps you can give me a small hint.
kind regards
Martin
