Multiple Category Selection widget is fantastic, but it breaks all site links when used with either of: wp-smart-sort, or sCategory permalinks.
I use multiple categories for each post. I therefore use ‘sCategory Permalink’ plugin so that I can nominate which category is the ‘primary’ category, but this ‘Multiple Category Selection Widget’ returns a search result with the category number, not the category name, eg:
so every single link on the /country/china/ page is broken…
unless I disable both ‘sCategory Permalink’ and ‘wp-smart-sort’.
Hoping someone can help, as all three plugins are great, but they just don’t work together.
