Is the database you’re trying to export big? If so, phpMyAdmin might be choking on the size. If that happens, you could try exporting the database in multiple parts, with a few tables per batch.
I tried the above suggestions, no luck. Then I tried different options. Turns out the “6) Click zipped compression at the bottom.”
is causing the problem.
If I use “none” or gzip compression, it works fine.
So my issue is fixed, I can download with no compression. But interesting that the “zip” compression causes a problem.
