I having the following problem:

I am trying to get the PHP Layers Menu (http://phplayersmenu.sourceforge.net/) working with MODx as Ralph did on Etomite (http://www.etomite.com/browsesnippets.html?int_snipid=81&lst_category=2), but getting a strange error...

When i open my site for the first time, and click on a submenu item, i am getting the following error:

Warning: Cannot modify header information - headers already sent by (output started at /chroot/home/brigitte/brigittedebiolley.be/html/manager/includes/document.parser.class.inc.php:452) in /chroot/home/brigitte/brigittedebiolley.be/html/manager/includes/document.parser.class.inc.php on line 416

« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource: 
« PHP Parse Error »

Parser timing 
  MySQL:  0.0233 s s (52 Requests) 
  PHP:  0.1286 s s   
  Total:  0.1520 s s

However, when i click again on the subitem, the error disappears and the menu is fully working...

Think this is related to the problem mentioned above?

Having this error now on other sites... And they don’t use the PHPLM-snippet, so that can’t be the cause of this error...

But now there are allready 3 sites of mine with this error, hoping on a solution...

Have you tried the temporary solution to disable the visitor logging? Works for me..

Hi all.
This error just showed up all of the sudden on a totally separate site. Disabling the visitor stats fixed it. Thanks for that fix!

Thought I’d add this comment in case it seemed interesting to anybody else that it would be fine for months (six, maybe?) and then just show up out of the blue one day with no changes to the site or server.

Also, not sure if anybody else gets this on their sites, but when I have visitor loggin on, I get this string of errors from the manager (you know, when you log in and it shows you the stats, that section gives these errors instead of the stats):

This table shows some visitor statistics for your site. For more detailed information, please visit the `Visitor Stats` page.

Hopefully that helps further diagnose the issue.

IMO, the "real" fix will be to remove MODx native logging altogether. It just plain s*cks, and I personally never use it, because of errors like this, issues with decreasing performance as log table sizes increase, and having to manually clean the db tables every week or two. There are 3rd-party statistics alternatives to using the native stat features that improve both performance and will avoid this problem, and the plan for 1.0 is to replace the current audit logging portion of this with a configurable native logging system that can send output to wherever you want it to (DB, apache logs, text files, XML files, etc.). See Jeff Whitfield’s (Bravado) blog post on Integrating Mint with MODx for some alternative approaches regarding logging visitor statistics.

In manager: Administration > System configuration > Log visits > No

Nothing to do with web users grunt_lord; this is plain old visitor stats tracking that is causing the problem, which, as doze pointed out, is easy to turn off. And! It was already a LOT of fun to rip it out of the MODx 1.0 core code that is in development...so maybe we’ll rip it out for the coming release. I need more FUN in my life! (ugh, I’m such a geek)
