Progress bars don work, whats wrong?
If you have this problem it may be difficult to tell unless you are familiar enough with G2 to know where to expect progress bars to appear. Examples are upgrader and G1 migrate.. if you don’t see a progress bar at all or it just flickers quickly on the screen when the request has completed then PHP’s output_buffering mode may be enabled. Check php.ini and make sure output_buffering is set to off and no output_handler is configured. If you are running Apache it can be configured with the deflate or gzip module and this will buffer all the output also. You can check by going to http://www.whatsmyip.org/mod_gzip_test/ and putting in your gallery url and it will tell you if the deflate or gzip module is being used.
