                if( !is_array( $rawEntry ) ) {
                        error_log( "\"$rawEntry\" is not a valid magic thingie for \"$mw->mId\"" );
                }
                $mw->mCaseSensitive = $rawEntry[0];

Line 1139       $mw->mSynonyms = array_slice( $rawEntry, 1 );


The warning also appears in the Apache log, but not the "magic thingie"
message (where does error_log go?).

Commenting out the line gets rid of the message but unsurprisingly this
affects the functionality.

Much Googling and experimentation hasn't helped.

Can anyone suggest a fix or workaround, or some way to get rid of the
warning?
