Error in error log after latest update

FYI — this keeps showing up

This is a network activated install and the error is only on the one (and only) subsite that I have. The main blog is fine. The user/permission is the same user for the entire database so it isn’t nor wasn’t a permission issue. How would I reinstall without losing settings?

Just a note too, this was not an issue until the latest update.

My theme is heuman: http://alxmedia.se/themes/hueman/ but I do have a custom child theme. There is only 1 sub site currently. Plugins are below.

Note the following are developed by me and not released yet: asd-global, pdf-indexer, simple-rss-widget. While nothing I wrote should be interfering, I know you’ll question it. pdf-indexer and simple-rss-widget definitely wouldn’t be doing anything. asd-global contains all of my wordpress mods. These are all of the hooks that I have doing something on:

Just thought of something to add– while I thought this didn’t start happening until the latest update, I also just turned on the wordfence dashboard widget, which I think I did at the same time.
