Up until two days ago, when I wanted to insert a link to a previous post, all posts showed up in the "or link to existing content" space. As of yesterday nothing shows up here nor does entering anything in the search field bring up anything other than an endlessly spinning circle. It's as if WordPress can't see any of my own content.
I've tried the following: disabled all plugins but the issue is still there. I've changed the theme to 2012 with disabled plugins but again the issue is still there. I've reinstalled WordPress from the Dashboard but still nothing. Any other suggestions? I can still link to my content by copying and pasting but this is a bit more cumbersome than it used to be.
I did install and then uninstall an app available through Attracta SEO on HostGator that searched for broken links on my website. I've since deleted it hoping it might solve the issue but it didn't.
I also have a pro version of Wordfence installed and all scans show no issues.
