“Stack overflow at line 72”

Hi guys,

I seem to get that “error” message when I click Login on the Meta section to log inside my blog DaveZan.com. I see it in IE, though not in maxthon or firefox.

What does that error message mean? I’m getting the impression there’s probably too much data going into something, probably the wp-login.php file.

If it helps, I’m including the line the message seems to be referencing that I’ve NEVER tinkered:

<input type=”text” name=”user_login” id=”user_login” value=”” size=”20″ tabindex=”1″ /></label>

It seems to have started when I uploaded Dagon Design’s Secure PHP Mailer Plugin. It happened after I activated it, yet the “error” message continues to show up even after I deactivated the plugin.

How can I possibly solve this? Any suggestions?
