First off. I count 7 posts from you on the same topic. This is not necessary.
The amount of memory allocted to PHP scripts is set to low. You will need to adjust it.
You can see the current settings in admin->tools->Host Tools
Your php.ini settings should at least be as follows.
safe_mode = Off
allow_url_include = Off
allow_url_fopen = On
register_globals = Off
upload_max_filesize = 1000M
post_max_size = 2000M
memory_limit = 512M
max_input_time = 30000
max_execution_time = 30000
short_open_tag = On
The one i marked bold is the one that needs to be changed.
NOTE: This is not a file included with dolphin as this is a hosting issue not a dolphin issue. You have selected a host that does not have the server setup to meet dolphins requirements per the hosting requirements. http://www.boonex.com/trac/dolphin/wiki/DolTech
If you have no php.ini file or do not know how to change it then contact your host. Some hosts allow a php.ini file to be created in the root folder of your site, others do not, and still others may require it in every folder of the site.
