Problem

You can't upload files larger than 2 MB in size.

Solution

If your server is installed as server module, and not as CGI module you could try to create blank text file, name it .htaccess and place it in your manage/ folder, and place following lines in it. If such file already exists, just append following code at the end of it:

php_value post_max_size 100M
php_value upload_max_filesize 100M
php_value max_execution_time 6000000

Otherwise, if PHP is installed as CGI module create blank text file, name it php.ini and place it in your manage/ folder, and place following lines in it. If such file already exists, just append following code at the end of it:

upload_max_filesize = 100M
post_max_size = 100M
max_execution_time = 6000000
