That is really strange. I am using PhpMyAdmin 184.108.40.206 on Linux hosting.
While I am Exporting databases using "gzipped" compression in Mozilla, I am getting files which have size of uncompressed database, but they seems to be downloading in incredible speed (10 times quicker than is possible using my ISP).
So at the end:
- for database of 10M size I am getting 10M gzip
- downloaded in miniseconds
- it has indeed shown 10M size on drive
- it is corrupted
Zip compression is working just fine (I am getting file with cca 1M size with fine content of compressed database)
And the weirdest thing: that is happening for Mozilla Firefox (13.0.1) only, Internet Explorer 9 is downloading correct gzipped files...
