Well, first of all, I'm using v1.3.9 and generally the first
time trying to setup PhpWiki...
In the theory you can define a 'prefix' for your database
tables (in index.php) to separate your table groups from
other ones in database! Nice feature but it doesn't work
so well since there are many queries in index.php (exactly
the '$DBAuthParams = array..' block) which do not make
use of this prefix and cause problem.
It will be great if you can somehow fix this in the next
version. For those guys having only one instance of a
database hosted somewhere, this is very useful.
