Description:
while installing i got following error
Checking environment...
[...]
Warning: mb_strpos(): Unknown encoding or conversion error. in
/data1/htdocs/mediawiki/includes/User.php on line 46
Version: 1.4.x
Severity: normal
OS: Linux
Platform: PC
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(Additionally, you're installing an out of date version of MediaWiki which contains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.)
I've added a fatal warning to the installation when this option is active, so it's
extra obvious things are going badly.
