Abandoned doesn’t mean ‘doesn’t work’ but does mean ‘potentially’ vulnerable.
I’m now looking for an alternative, as I now tend to remove any plugins that have been abandoned……the risk is just too great.
I’ll report back, but I’m going to try ‘Pages with category and tag’ (https://ww.wp.xz.cn/plugins/pages-with-category-and-tag/) or with Create and Assign Categories for Pages (https://ww.wp.xz.cn/plugins/create-and-assign-categories-for-pages/).
I’ve also contacted the author to see if he plans to update ‘this’ plugin.
There is so little code in it that i think it’s not a security risk.
