Hi,
When I log into my site, as an ADMIN I got a WSOD.
Als a normal user, after login, I see the frontpage.
No errors found for PHP or in logfiles.
Only the watchdog table gives some hints. I went to the login page, which behaves normally, truncated the watchdog table. Login in as admin, then WSOD.
1.) uid:0, type:access denied, message:frontpage, severity:4 {login page, after browser refresh CTRL+F5}
2.) uid:1, type:user, message:Session opened for %name., severity:5 {after login}
