NorrCompetition white page
Do not think that it's something NorrCompetition related. Have you try the default template, for example Protostar? Currently we should not have any issues with any templates.
Can you try it without sample data? I am not sure, but it is possible that sample data can cause errors.
Also white page means that there is some error, but it is hidden. Here is good and simple tutorial how to find out, what this error is.
Ok, I tried unisntalling and reinstalling component...
Hidden error is:
Fatal error: Cannot redeclare class CompetitionRouter in /web/htdocs/www.cooperazionemilanese.org/home/components/com_competition/router.php on line 452
Hmm, that's really strange error. What menu link you are trying to open?
May be you can provide temporary user and pass (also ftp) to your site and we will try to explore the problem and find the solution. You can send credentials to support [at] norrnext.com.
After playing around with your site I found an issue that leads to fatal error - there is some kind of conflict with sh404SEF component. When I disable URL optimization in it then there is no fatal error. Unfortunately I can not debug further, because I do not have FTP access.
sh404SEF is a paid download and that's why we cannot test our component with it. If you can send us your version of sh404SEF then I will install it on my test website and try to make a fix for this conflict.
I think I found an issue and I hope that fixed it. We have send you a version with the fix. Looking forward to your reply.
