Reply To: ERROR: Sorry, this file type is not permitted for security reasons.

It’s been at least a couple years since anyone has had this WordPress error shown and the fix was as simple as changing the file name.

I know one other user is having the exact same issue. It is either a coincidence or perhaps the last security update WordPress pushout out a few days ago changed something that might have affected a very limited number of users in regards to csv file uploads (so far you and one other).

To learn more and address the issue, I’ll need a temp WP admin login and a FTP login. You can post the login details here as a private reply. Once I have the logins, I’ll take a look asap.
