So I changed php.ini to zlib.output_compression = Off but I don’t think this is the best solution.
See https://stackoverflow.com/questions/38693992/notice-ob-end-flush-failed-to-send-buffer-of-zlib-output-compression-1-in

Ran export (with zlib.output_compression = Off) and new browser window with readable code but failed to create a downloadable csv file.

Thoughts?

How can I post a picture?

Here’s a sample of the code:
`??V[o€6~???b??!u≥‰?@∑?[a????ú$Pe≥?%?§?∏Eˇ?IKvba?ü=¨@ò?o?xz≈d.?oPo>??r????NU?}5od’

I thought maybe the character or collation was the issue but I can export the users as readable csv files in two other plug ins and directly from mysql as csv files without issue.

Sure, do you want a file or try to post the text here?
