[Chameleon] error rendering map image after reinstalling

[Dejan Gambin]

Thanks everyone,
 
The problem was indeed in my map file, I have ignored the warning about my
symbol definitions that caused the error even I don't know why because they
worked ok on my previous installation.
 
Anyway, it is solved now.
 
regards, dejan

Hi Dejan,

If the samples are working then it is either a problem with your template or
mapfile.  I would start with the mapfile.

Try loading the map using a simple php script like:

<?php
// load the mapscript module if necessary
if (!extension_loaded("MapScript"))
{
    // load
    dl( 'php_mapscript_46.'. PHP_SHLIB_SUFFIX );
}

// open map
$oMap = ms_newMapObj( 'mymap.map' );

// force output
$oMap->selectoutputformat('png');

// draw map
$oImage = $oMap->draw();

// set header
header('Content-type: image/png');

// output map
$url = $oImage->saveImage('');

?>

If that works then the next thing to try is removing all your widgets from
your template and start putting them back in one at a time to see where the
problem is.

HTH

Bill
