404 errors caused by Ecwid URL processing

Hi there,

This is an obscure one, but…

We have an Ecwid shopping cart on a site at kingscliffeheritage.org. We also have an extensive records archive, with a lot of date-based post slugs. Some of those slugs end with a circa year in the format blahblahblah-c1986. For example: https://kingscliffeheritage.org/catalogue_item/golden-ball-ground-floor-basement-plan-c1970 – all of those URLs currently result in a 404 error.

Digging into it all, the problem goes away if I disable the Ecwid plugin. If I go into the code, this function in includes/class-ecwid-seo-links.php appears to be the culprit:

protected static function _get_pb_preg_pattern() {
return '!.-(p|c)([0-9]+)(\/.|\?.*)?$!';
}

That doesn’t appear to have any checking of the URL for the shop prefix, so it will match with anything ending in -c1986 or whatever and presumably attempt to convert that into a shop URL, which it won’t then be able to find. If I comment out the return line in that function, the URLs work fine (but I presumably break the shop!).

Any ideas, please? Can we add the shop URL prefix to that Regex pattern, so that it’s more specific? Any help gratefully received.

Many thanks,

ian.
