I appreciate your prompt attention to this. I am continuing to receive the following error at https://fywp.emuenglish.org/?page_id=207, unfortunately:
Memphis Error: Sorry, this file type is not permitted for security reasons, contact your administrator for more details.
If you are running Multisite you can add this file type from the Settings menu of the Network Admin.
I have confirmed that I am not running multisite. The plugin is updated. I can see the selectable (or deletable) filetypes listed in the settings tab, and xls is among them. I have also tried to upload the file as media, and WordPress accepts it. I can upload a .xlsx file, but I have tried to run it with a couple of different .xls files, and the error returns. I also tested it from different user accounts with no luck.
