I discovered the issue from other forums. If you have WordFence installed on other websites that are on the same server, delete WordFence on them also. I did that and the issue immediately went away. I have been using Wordfence for years and I am sad to see so many issues posted within the last couple of weeks and no update to the plugin on www.ads-software.com for two months. There is obviously an issue, hopefully, some updates in the future!
