Cumulus Support

Hi.
I've got a problem with extra web files. Cumulus creates files on server 000 Webhost (http://www.000webhost.com), but these files are empty! For example realtimegauges.txt is empty. But if I open file in file maneger I see all data inside the file. I have the same problem with realtime.txt. All realtime files are updating every 30 seconds.
I don't know where is the problem with server or with cumulus?
What can I do?

000webhost don't allow the use of .txt files.

Thank you.
