No, dbm*() functions come from compiling PHP with --with-dbm.
Functions using gdbm start with dba_*()
According to the PHP docs one should avoid dbm and use gdbm instead.
Maybe we should consider switching.

Aha! You don't have dbm support in PHP.
Judging from your phpinfo() output:

         dba
        DBA support           enabled
        Supported handlers    gdbm=20

There are two different functions for dbm-style databases in PHP.
One is the classic dbm interface, one is an abstraction layer interface t=
o=20
dbm-style databases like e.g. gdbm, ndbm, Sleepycat's db2, ...

Right now you use the abstraction layer. phpwiki makes calls to the class=
ic=20
dbm interface. Thus: function not found - and phpwiki can't operate. It's=
=20
strange however, that you don't get the error message from ExitWiki().

Short term solutions for your problem:

- compile php with --with-dbm (note the missing 'g').

- Otherwise (if you don't want to recompile PHP): replace all dbm*()=20
functions with their dba_*() style counterparts. Unfortunately, you will=20
have to modify the arguments as well. If you are new to PHP this might be=
=20
too much trouble.

- Otherwise: switch to another database. mySQL, msql, and PostgreSQL are
  supported. I don't know if the flat file system is ready for use just y=
et.


Long term solution:

Steve should check if it's not better to migrate to the dba_*() interface=

Permissions look ok.


Hope that helps.
