Re: PEAR shaped SourceForge installation.
If you want to tell Tiki to use the local PEAR rather than the global PEAR (seems required for SF.NET hosted Tikis), you will have to edit the file db\tiki-db.php.
On line 8 you will find:
// $api_tiki = 'pear';
Uncomment this line and you're done!
EDIT 17/08/2004.
Sorry, that's not the solution either.
I'm still lost. I keep getting:
Fatal error: Cannot redeclare class pear in /home/groups/p/pc/pcrobots/htdocs/lib/pear/PEAR.php on line 67
Perhaps if mose has time to read his messages, we'll get help?
