You will need increase memory ask you hot if they can increse.

Using FTP, try increasing the memory for PHP and WordPress by editing the memory_limit line in your php.ini (if you have access to it) to 64M:

memory_limit = 64M;

If you can’t get to the php.ini file, add this line at the top of your .htaccess file:

php_value memory_limit 64M

If that doesn’t work or throws an error, add this line near the top of your wp-config.php file right after the opening <?php

define('WP_MEMORY_LIMIT', '64M');

If none of those work, your host probably doesn’t allow memory allocation overrides. You’re stuck with what they give.

ok, I am looking for my php.ini file, I don’t find it… either to htaccess, I will tell you later, I am searching… thanks for your help!

I have try the option 3, didn’t work. I have contacted the hosting, let’s wait what they tell me…

Ok, I spoke to my host-service so they gave me more capacity in php ini, I have imported all files.
Thanks for your help!!
