I made a new Target List and was able to add 620 contacts to the list, but every time I try to add more the screen locks up. Is there a different way to add contacts to a Target List?
How are you adding them? Is it the browser that is freezing, or is it the application?
You may need to increase the ‘default_limit’ value in config.php to say 10000 instead of 1000, and you may also need to get your web admin to increase timeouts in your php.ini
