the first thing I have to say: Piwik is a very nice tool.
Now, I have a problem with the tool.
Yesterday I updated to the newest version and it worked fine.
But today I always receive following failure while entering the tool:
fwrite() expects parameter 1 to be resource, null given in '/users/jmp/www/piwik/core/Piwik.php' at the line 999
There are also some more lines, but I hope that this is enough.
I hope that you can help me.
