Sally: If you want to find the Max memory size for your site, you can create a new php page and add the following code to it after the <body> tag:
<?php echo("memory_limit: ".ini_get('memory_limit').""); ?>
this will show just the memory limit setting
if you wanted to see all of your PHP settings, you could use this code:
<?php phpinfo(); ?>
Thanks! Looks like my limit is 32MB. Nice to know for the future.
Thanks so much for all the support!
