take baby steps here;
>> - I've installed my .crt en .pk files
should be .crt and .key
also, set the names of both on the webserver security tab.
>> in the "certificates" folder below the webfolder,
should be in certificates folder, below exe, not in web folder.
>> but I think the nettalk server moves them upwards (so it is able to find these ...). Is this intended?
yes, putting them in web folder is a mistake the server "sees" and allows for.
>> - additional question : I can rename the .crt and .pk file to anything I want to as long as it matches the two corresponding prompts in the webserver setting, right?
correct, but you need a key file, not a pk file.
