Tier 2 category WordPress

Hello

First of all thanks for thinking on creating a script for this problem.

I just tested the plugin and on 4.2.2 with multisite and active subcategories the plugin returns a 404 with a /%category%/%post-name%/ permalink.

Example current url with the plugin active, with the above permalink.

domain.com/category/article – works
domain.com/category – works
domain.com/category/subcategory – 404
domain.com/subcategory/article/ 404

If I add manually /blog/ before url in the 404 from above, the link works, just not by the without old blog path suppressed by the plugin.

Help.
