Description philipp 2005-10-23 12:19:30 UTC

while installing i got following error
Checking environment...
    * PHP 4.4.0: ok
    * PHP server API is apache2handler; ok, using pretty URLs (index.php/Page_Title)
    * Have XML / Latin1-UTF-8 conversion support.
[...]
# Initializing data...
# Granting user permissions...

Warning: mb_strpos(): Unknown encoding or conversion error. in
/data1/htdocs/mediawiki/includes/User.php on line 46

That line is:
if ( $wgUseLatin1 && ! ( strpos( $name, chr( 0xAD ) ) === false ) ) {

strpos(), *not* mb_strpos(), is being used. Probably you have the 
mbstring.func_overload option in PHP on; this option is very likely to cause data 
corruption and various problems and should never be used ever by anyone. Turn this 
off if at all possible.

(Additionally, you're installing an out of date version of MediaWiki which contains 
known security problems. Please install a current release; the most recent 1.4.x is 
1.4.11; 1.5.1 is the current recommended version.)

Comment 2 Brion Vibber 2005-10-28 09:04:07 UTC

I've added a fatal warning to the installation when this option is active, so it's 
extra obvious things are going badly.
