Magento: Cannot add new attribute option values or delete after adding too many values
I've been trying different fixes for the issue mentioned but the fix below is the best. To fix this issue, do the following in php.ini: memory_limit = 256M max_execution_time = 3600 max_input_time = 600 post_max_size = 512M max_input_vars = 100000 suhosin.post.max_vars = 100000 suhosin.request.max_vars = 100000 You may add some lines if they don't exist yet. In CentOS, php.ini can be found in /usr/local/lib/php.ini. In Ubuntu, it's residing in the following : /etc/php5/apache2/php.ini /etc/php5/cgi/php.ini /etc/php5/cli/php.ini After modifying php.ini, please don't forget to restart Apache. That's all!
