Thread:Project:Support desk/MW 1.23 Category pages not being linked if spaces in name but works with

So I've upgraded to MW 1.23 with MariaDB on RHEL 7

Al is good except some of the pages belonging to categories are not being displayed.

e.g. if I add this category link at the bottom of a page, it will ink to the category from that page but the page will not be listed from the category

However, if I use the following format for the category name, everything works - link to the category appears on the page & page is listed under the category page.

My problem is that most of the category links were created in the first format which worked in MW 1.18

Any suggestions on how to resolve?

Thanks
