I am trying to upload an .OFT file which we have uploaded many times in the past. I am getting an error message which says:

Upload blocked. The file type is invalid-the file extension does not match the actual content type.

I have tried new OFT files as well as previously uploaded ones. All receive the same message now.

WP Download Manager Version 3.3.15
WP Version 6.8.1

Hello,

I hope you are doing well and thanks for reaching out.

kindly use this hook add_filter("wpdm_is_valid_mime_type", '__return_true'); in your theme’s function.php file. This should fix the issue.
Please check and let me know.

Regards
