JavaScript tag striped out from templates when editing from Admin

Question

I am running ExpressionEngine 2.5.3. Happens something weird: when I save a template from the admin panel, javascript tags in it gets transformed from <script> to [removed]. I have checked file permission, configuration etc, but I can't figure out why this happens.

Answer 1

I've seen this happen when the server was doing some aggressive security stripping. Modifying the template via FTP didn't show the issue; only submitting via the CP. So I'd talk to your host about it; and also try via FTP and make sure that works as expected. :)

Answer 2

If it's full javascript, you're using the wrong template type. While the web page template type will handle references to javascript files, such as

<script type="text/javascript" src="/javascripts/modernizr.foundation.js"></script>
<script src="/javascripts/lib/selectivizr.js?1337120337" type="text/javascript"></script>

the javascript file-type is preferred for actual javascript. Read, 'Are There Limitations on ExpressionEngine's Javascript Handling?' question by Steve Hurst. The web page template doesn't always protect javascript, so it's frequently better to reference the script and store outside of EE or on the javascript file type. But another option, which may work is to modify the config.php file to add the hidden variable:

$config['protect_javascript'] = 'y';

ExpressionEngine has a number of, not needed frequently, but available for use variables, see Hidden Variables.

One of these should work, assuming there wasn't some odd bug in EE 2.5.3. Is there a reason you haven't updated to 2.5.5? You may also want to upgrade.
