My URL doesn't recognise ZERO! Need help please.

Hello,
Recently, a freelancer updated my site from 1.5.3 to 1.5.4 and transforming to "mobile".
I haven't noticed then about the issue, and I cannot find the freelancer.
Here is the problem: I am selling on my site several products which use the mains (110V or 220V).
I assume that I am not allowed to post a link, so I will write just an example: The product uses 110V - or - 110 to 220V product.
This is written on title. After saving it appears on the URL: The product uses 11V - or - 11 to 22V product!.

The "zero" disappears!!!

Any help please?
Thank you in advance,
Ridgh

Don't have a solution at the moment based on what's been provided, but the link as far as being displayed here is permissible, but up to you if you want to post it:

Which URL rewriter plugin are you using?

Which URL rewriter plugin are you using?

LOL... I have no idea... it is done automatically, isn't it?? :dontgetit

As you can see, at the end of each page also appears "p-xx" as "p-22" and I don't know how to get rid of it.

Thank you,
Ridgh

Thank you lat9,
I found one of the problems: in Ultimate URLs, - Enter PCRE filter rules, there was a zero (0). I removed it and it appeared.
It remains only the "p-30.html" problem.
Is there any way to delete the "p-30"?

When I go to the above website, the URL on the listing page was "/uhf-stabilized-by-quartz-c-5/110-or-220v-uhf-mains-operated-room-bug-flat-v3-without-battery-p-106.html"... Looks like it is working as expected...

Can you share what you needed to do (for others reading this thread)? Or did it just "fix itself"?

Hard to say more without knowing which alternative URLs plugin you have installed (and the version)...

I've replied twice to the thread - and it hasn't been published...
I fixed the main problem:

The 0 appears on "PCRE files rules".
I've removed it and now it appears OK. However, the second question, regarding the page or category number remained open:
on the URL appears :"product_XXX_p_107.html". How can I remove the "p_107" from the URL?

All links show fine here - can't see a 'discarded' zero

Sometimes posts are temporarily moderated for manual review before they are released ... several of your posts were moderated and had to be manually released ... sorry for the delay ...

Ridgh:

... The 0 appears on "PCRE files rules".

Having a 0 there would translate to: preg_replace('/0/', '', $title); and cause the reported problem. Thank you for letting us know removing the problematic filter fixed the issue. For any who may come across this thread later, the default is blank (no PRCE filters) when installing Ultimate URLs.

Ridgh:

...
on the URL appears :"product_XXX_p_107.html". How can I remove the "p_107" from the URL?
As per the support thread for Ultimate URLs, those "anchors" are required. For more details go read the support thread (this has been asked MANY times and answered with details including pros / cons MANY times).

If you want "full control" of the URL, switch to CEON URI Mapping. Be aware you may need to leave / adjust the existing RewriteRules if switching to avoid potential loss of ranking in SEs.
