I know this question has been posted here, but I can't seem to fix it.
The problem is that Drupal needed more memory than php was allowed to give it.
running a phpinfo() I find the configuration file path is: /Applications/MAMP/bin/php/php5.4.10/conf/php.ini and I adjusted that file. (memory_limit = 1028)
I also adjusted: main php.ini (MAMP/conf/php5.4.10) drupal settings.php (MAMP/htdocs/drupal-7.24/sites/default/settings.php)
nothing seems to work.. any help is appreciated
