[Mediawiki-l] ParserFunctions seem not to be working

[Frank Middleton]

In solving a problem with maintenance/dumpBackup.php (fixed by using
php5 -c /path_to/php.ini) I found this in the previously disabled log

"" is not a valid magic thingie for "#expr"
"" is not a valid magic thingie for "#if"
"" is not a valid magic thingie for "#ifeq"
"" is not a valid magic thingie for "#ifexpr"
"" is not a valid magic thingie for "#switch"
"" is not a valid magic thingie for "#ifexist"
"" is not a valid magic thingie for "#time"

It seems that wfParserFunctionsLanguageGetMagic isn't being
called for some reason. The following line was commented out
in ParserFunctions.php

$wgHooks['LanguageGetMagic'][]       = 'wfParserFunctionsLanguageGetMagic';

but uncommenting it appears to make no difference. Could one of you
php gurus out there suggest a way of debugging this? Doubtless the
non-working [[subst...]] fails for a similar reason. Editing the
php files isn't a problem but the internals of the hook logic is
somewhat inscrutable to a php neophyte. Looking for tips, not a 
fix. Thanks!
