Hi, this happens because of max_execution_time, memory_limit and maybe because of upload_max_size limit. Those are server settings that can be changed. You can ask the host provider to increase the limits or you can change them in php.ini file:

memory_limit = 256M

upload_max_size = 64M

post_max_size = 64M

upload_max_filesize = 64M

max_execution_time = 300

max_input_time = 1000

or in .htaccess file:

php_value memory_limit 256

php_value upload_max_filesize 64M

php_value post_max_size 64M

php_value max_execution_time 300

php_value max_input_time 1000
