[pmwiki-users] Ghost pages in 2.1.5

[Chris Cox]

I tried deleting some pages in 2.1.5... I tried deleting them with the normal
delete, I've tried removing the files (including the del- files).  But when I
do a search (e.g. group=Hosts), the returned list includes a non-existent
page link to the page I deleted.  Where on earth is this coming from?
I've tried removing the .pageindex and restarting apache.  What am I missing?
