Strangely the smarty debug window does not appear anymore while it did before.

1. I have switched the debug mode to smarty (retried to set it over and over again)
2. In the source of the page I see the smarty code at the bottom of the page.
3. I do block pop-ups but on other sites I get a warning; for my site I do allow pop-ups.
4. When I switch to PHP debug I get no error

Help! Does anybody have any idea what the cause of the problem can be?

Even switching both the theme and templates to the default did not change anything. So no problem there.

Th problem occurs both with internet explorer and Mozilla.

I had a similar problem once. It turned out that I was blocking Javascript or popups for that domain. You're sure you're not doing that?

If you need a temporary workaround, you could insert this in a template so that the Smarty debug output will appear inline:

Hey man, thanks!

Because of your remark I started re-thinking the blocking. Since I did see pop-ups being blocked elsewhere I thought this couldn't be the issue.

Since the problem occurs in both Mozilla and internet explorer it had to be something outside the browsers. First I thought of XP's firewall. But that was switched of ... because I have Norton on my system! Tatata! There the solution was.

A few days ago I had to simulate the situation of a customer who didn't see the ads on our website. It appeared that he had the privacy filter of Norton switched on. I forgot to put it back.

Now it works as it did before, this feature I use so often!

Thanks again!
