Question

When saving a CMS block in Magento 1.4.1, I am getting an error, connection reinitalized by my web browser. I only get this this error, when adding the tags <script></script>. Any other changes I can save and I can add new blocks as long as I don’t use <script></script>

The only error I’m seeing is in /var/www/website/var/log/exception is this and only if I hit F5 after getting the connection reinitalized error. Apache and other system logs are not reporting any additional errors.

This website was working fine on a Centos 5.4 with PHP 5.2.13. All the same Apache and PHP modules were installed on the new Debian server. Any help would be sincerely appreciated.

Answer 1

A rule in our Netasq firewall was blocking the <SCRIPT> tag. Once we disabled the rule, the client was able to use the tag again. We did warn him, however, that netasq probably put that rule their for a very good reason.
