Empty login page on an animal site (“Greebo” on PHP 5.6.21.) #58

Hi, thank you for your nice tools. I found the animal site's login page has been empty on the newest dokuwiki.

I created an animal site, and tried to login to it, click the "login" link, then the screen became empty (blank).
On the farm site, I can login it as usual.
With debug mode, dbglog($msg) to the inc/Action/Login.php did not show any log.
The environment : “Greebo” on PHP 5.6.21. CentOS7 (4.14.33-300.1.1) (With “Frusterick Manners” on PHP 5.3.3, CentOS6(2.6.32-642.6.2), I can login the animal/farm sites as usual.)
I tried with dokuwiki and vector templates.

an empty page is always a sign of a fatal error. See if you can find an error log for your PHP.

Yes, some brower(chrome) suggested it was 500 error, but I had no error message in the HTTPD log. (The environment was on a hosting service, so I could not grab the error message. Sorry.) By the way, I found that the issue was related to the Farming->Configuration->Plugin State setting. When I disabled the setting, the issue was reproduced, but not when enabled. (I slightly relieved that I might be able to operate my site. ) I rechecked on the “Frusterick Manners” on PHP 5.3.3, the issue was not reproduced. It was reproduced only on Greebo.

Could you try installing the showphperrors plugin and activate the showphperrors option? This might print out the fatal error. (Don't use this plugin except for debugging. It might break other things or leak sensitive data)

Oh, thank you. After installed the showphpeperrors plugin, I found that the problem was caused by the fedauth plugin. I had disabled it before, but it was needed to uninstall it. Thank you for your help and nice tools.
