Issue: after configuring phpwiki with the configurator, loading
[hostname]/wiki produces no output whatsoever. No error in error logs.
No contacting the DB at all (watching mysql query log)

Running (from memory)
php -f < index.php
from the cmd line in a term , as root, populated the DB with pgsrc as it
should.

after a very interesting trip into the guts of phpwiki, i realised the
culprit was the call to pear's DB.php in  lib/WikiDB/backend/PearDB.php ,
@require_once('DB/common.php');
Removing the @ showed the following in my error log:
---
Feb 20 00:03:53 sigma httpd: PHP Fatal error:  wikidb_backend_peardb():
Failed opening required 'DB/common.php'
(include_path='/home/httpd/vhosts/xxxx/subdomains/yyy/httpdocs/wiki:/home/httpd/vhosts/xxxx/subdomains/yyy/httpdocs/phpwiki-1.3.11p1:.:/usr/share/pear:/home/httpd/vhosts/xxx/subdomains/yyy/httpdocs/phpwiki-1.3.11p1/lib/pear:/home/httpd/vhosts/xxxsubdomains/web20/httpdocs/wiki/lib/pear')
in /home/httpd/vhosts/xxx/subdomains/yyy/httpdocs/wiki/lib/Wik
---

include path in my config.ini includes /usr/share/pear.

Anyway, my commenting out that initial call to look for the PEAR file,
it simply did a silent fallback to the DB.php included with phpwiki and
everything seems to be sorted. Please note that , although this should
be the default fallback, the script was FAILING on that first
require_once line , silently, and no output whatsover generated.

Is there something obvious i'm missing ? Something wrong with my setup?
(I understand the issue is that the php instance in my subdomain
couldn't locate the pear files , although it was the path was defined in
the include path setting....)

I can provide other info as needed for proper documentation / fix.

Beto
