    This error throw because default setting is low and not enough memory to do.

    You can open file php html and add line code bellow into top of file:

    <?php ini_set('memory_limit', '1024M'); // or you could use 1G

    I hope it solve for you.

    You can edit value of memory_limit in php.ini file. You need to increase it to double.

    Step 1. Run vi /etc/php.ini command in your Ubuntu server and change memory_limit to double. ex: change from 125M to 250M.

    Step 2. Run /etc/init.d/httpd restart command to restart Php server.

    I hope it solved for you.

    You can change memory_limit from .htaccess file. Open .htaccess file and change as below:

    vi ./.htaccess
php_value memory_limit 256M

    It worked for me.
