Problem with redirects

[badarac]

I'm having a problem that's a real head scratcher. When you enter a search term that is not found it gives the message:

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

A valid search works correctly. This site was recently upgraded from 1.3.9 and has the CEON URI mapping mod installed and active. PHP 5.3.29 MySQL 5.5.41-cll-lve. A complete list of mods is:
blank sidebox
advanced shipper
ceon uri mapping manager
ckeditor
email archive manager
google analytics
image handler 4.3.2
cowoa 2.4
mydebug backtrace
numinix facebook lke button
product listing sorter
tabbed product pro
thub
timezone fix
ty package tracker

There a no errors being logged and the server logs are not showing anything. Anybody have any suggestions on how to debug this? Here's a link to the site if you want to see the problem http://tinyurl.com/qay5dhe

Just a quick update. The hosting company was able to see the following in the logs:
Its actually causing a small flood, you can see here in the access logs (only the first copied):

x.x.x.x- - [03/Mar/2015:11:21:44 -0600] "GET /index.php?main_page=advanced_search&search_in_description=1&keyword=sebhor&inc_s ubcat=0&sort=20a HTTP/1.1" 302 24 "http://domain.com/"; "Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko"
x.x.x.x - - [03/Mar/2015:11:21:44 -0600] "GET /index.php?main_page=advanced_search&search_in_description=1&keyword=sebhor&inc_s ubcat=0&sort=20a HTTP/1.1" 302 24
You can see its 3-4 times a second, that is your IP so its obviously not malicious. It doesn't appear to be from htaccess so something like an internal PHP redirect. Do you have any mods that use rewrites like SEO?

So it seems it's related to the CEON SEO mods.

To validate your theory, you could temporarily turn the Ceon SEO 'off' ...

Additionally, I noticed:

&inc_s ubcat=0&

Is there really that space between &inc_ and ubcat?

[badarac]

No extra space. It must have been from the cut and paste. I tried turning it off and interestingly it does not make a difference. This is the only situation where it happens and the rewrites work perfectly in all other pages and it works correctly if the search term is found.

This is almost always the case (can happen with any SEO mod that doesn't take everything into consideration, or one that has additional rules added to the .htaccess file (possibly in the wrong order).

The answer is No. Here's what the actual URL shows.
index.php?main_page=advanced_search&search_in_description=1&keyword=QWERTY&inc_s ubcat=0&sort=20a

Try renaming or removing the .htaccess file. Does the problem still persist?

With the htacces file renamed and the seo mod turned off it still happens. I guess I'm going to need to look at the search form and what happens when it doesn't find a match.

Oooer. I think you may be in to something here. I just noted that MY cut n paste also has this space. It ISN'T showing in the URL though.

I think some kind of odd character has managed to creep in somewhere that is messing with things.

More investigationing needed.

See my next/previous message. We appear to be barking up the wrong tree.

There is *something* amiss with the "inc_s ubcat".

Offhand I don't know where that is set or defined, but find and fix that and you'll probably fix the issue.

More investigationing needed.

templates/tpl_advanced_search_default.php (or the same named file in your CUSTOM_TEMPLATE folder)


Probably around line#35

<?php echo zen_draw_checkbox_field('inc_subcat', '1', $sData['inc_subcat'], 'id="inc-subcat"'); ?>

Re-enter the 'inc_subcat' in both places, even if it *looks* ok. (type it. Don't cut n paste)
