Issue with AMASTY Shipping Rules Extension

[ateschrist2804]

Amasty Devs aren't much help unfortunately..

Extension: Shipping Rules

Issue: Mass Insert comma-separated US zip codes

The .csv has been validated and there is nothing wrong with it.

When entering a mass quantity of zipcodes and saving it, nothing happens. The page refreshes back to the dashboard and then the zone i just created never shows up under "shipping rules" in the extension.

@ateschrist2804 Have you checked by trying to increase the post_max_size variable value from php.ini

please check the value of this varible in your php info file.
If you don't have such file then create a php file as info.php on the root of magento directory and paste the below code in it.

<?php
echo phpinfo();

Then try to fetch this file in browser as yourdomain/info.php

Thanks
