Manual talk:$IP

The file LocalSettings.php has the paragraph

# If you customize your file layout, set $IP to the directory that contains

# the other MediaWiki files. It will be used as a base to locate files.

if( defined( 'MW_INSTALL_PATH' ) ) {

$IP = MW_INSTALL_PATH;

} else {

$IP = dirname( __FILE__ );

}

Should this paragraph be edited for the setting up of the mediawiki?

Should the string MW_INSTALL_PATH be substituted to some sequence of characters, specific for the custom server?

Should the string dirname( __FILE__ ) be substituted to some sequence of characters, specific for the custom server?

Can this setting be responsible for the error message Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert):

Is it possible to put the answers in the article?

Such an explanation would help to indicate the path in such a way that the mediawiki finds the programs it needs. Tori 19:07, 6 March 2011 (UTC)

"MW_INSTALL_PATH" is a constant. It must not be changed. dirname() is a php function, which automatically returns the right sequence of characters. The block of code is fine as it is. :-)
