Some Canonical urls aren't working

-- HikaShop version -- : 2.6.0

Hi Hikacrew !

Well the site is finally online !

I seem to only have one slight problem (so far).
When you got to the URL ( I included), and try clicking on the first and second products you'll get a 404, but not on the third, that one' seems to be ok. Mind you they all have the exact same settings and identical url paths.
I tried changing the URL in the canonical section, but that doesn't seem to work.
It worked for a few different products throughout the site I fixed, but theses one's won't or don't. change.
So, I was wondering if you might know why ?

Let me know if you want access?
Thx.

Hi Nicolas;

Yeah, I 'm aware of those points you mentioned, but nothing I do to canonical url changes anything.
I always get a 404 page.
It's very strange.
Maybe I should do a repair database table or something like that ?
Any other ideas?'

Thx.

Hi,

If you disable the canonical in Configuration > Features > SEF Urls are you able to reach the products ?
Could you give us a screenshot of the configuration of the "tanga" product ?

OK i tried to disabling the SEF, and when I click on the TANGA it take me to the index.php (homepage) , (very strange).

And here's the screenshot.

Could it be a server configuration problem ??

Hi Nicolas;

I tried that... but that hasn't changed anything.
So I did some investigating, and here's what i found.
Compared Panties to G-string in the DB and all the settings are identical.
So, then I decided to recreate a product : Panties.
Didn't want it conflict with the unpublished original Panties, so I called them: Latex Panties.
And that worked, it displayed no problem. So once that worked, I decided to delete the old Panties product from the Hikashop.
Then I decided to restore the old name of : Latex Panties to just : Panties.
And that is where it stop working.
It seems that if the product only has one word, something, url related, fails.

Your take ?

Hi Nicolas;

Humm, no there are no other things named the same, like what you mentioned.

For now, I've just added another word to all single named product aliases and it works; not really a fix, but it's a solution for now.

Maybe when I update to 2.6.2, it will fix the problem?

Thanks for your help.
