The problem isn’t magic_quotes_gpc neither the PHP version 5.3.28 that I use. I have tested it and changing to PHP version 5.4 for a short time doesn’t help either.
I can’t use the command line and cron jobs on the hosting server but it wasn’t necessary before.
As I wrote before the configuration of magic_quotes_gpc doesn’t solve the problem.
The following error appears with PHP 5.4 (without the possibility for magic_quotes_gpc):

Then if you still have the problem (which should be the case), could you email me matt@piwik.org your server information (SSH) so I can connect + reproduce the issue on your server? This would be really helpful! thanks
