Unable to upload file for importing

Unable to upload file for importing

When you try to import your subscribers from a text or csv file, sometimes you might get an error like:

Your form has a few errors, please fix them and try again!
The file "filename.csv" cannot be uploaded.
Only files of these MIME-types are allowed:
text/comma-separated-values, text/csv, application/csv,
application/excel, application/vnd.ms-excel,
application/vnd.msexcel, text/anytext, text/plain.

This happens because the file you try to upload does not have the correct mime type, i.e.: you upload a csv file, but it is identified as a text file, and it’s not allowed.
In order to fix this problem, you can go to Backend > Settings > Import/Export and set “Check mime type” to No, then try uploading the file again, this time it will work.
