CASLogin plugin: Blank login page

Hello,

I’ve just installed Piwik 1.10, and the CASLogin on a new CentOS server.

I’ve disabled the Login plugins and configured the CASLogin as my others piwik servers.

But when I’m going on my piwik page, I’ve got a blank empty page. No link “connection” which send me to the CAS like my others servers.

I don’t understand why… Nothing in error log of apache.
Where is a way to show debug informations?

Another thing: If I manualy go to my CAS server login page, and log me, then if I return to my piwik page, I’m logged…

If anyone have an idea?

I hope you understand my english, because I’m french and I don’t speak english very well…

Thanks!

please ask on the CASLogin plugin page
