"Nothing Found"

I turned debug on. I do not get any errors or notices on the category pages where I am getting the “Nothing Found”, but I do on the homepage. Here they are:

Notice: Trying to get property of non-object in <path>/wp-content/plugins/reorder-post-within-categories/reorder-posts-within-categories.php on line 98

Not sure why, but I believe the categories were all changed to the content type in the database. I fixed this by going to reOrder (in the content type), select a category, select ‘No’ manual sorting, then select ‘Yes’ manual sorting again. This has to be done on each category that is displaying “Nothing Found”.
