[pmwiki-users] Users not logged in get a blank page

[Petko Yotov]

Let's say that we need to first try to fix the blank pages problem and 
then the SMF integration (unless it is the integration that causes the 
blank pages).

Also: there appear to be 3 addons for SimpleMachinesForum integration in 
the PmWiki cookbook, which one do you use?
