Hi everyone,  
Recently, I can’t get the right analysis from the LogMuncher. I just download the “.px4log” via the QGC, and upload in the LogMuncher. Then, I get nothing… 😭 How can I get the right analysis as before? Thanks.

Did you try refreshing the page?  
Also, try to use px4tools. You may also try flightplot.  
Alternatively, you can convert px4logs into csv and write your own code to plot the px4logs

It’s a bit confusing because the log format changed, but QGC appends the file extension. Check the actual sdcard. Do you have .ulg files or .px4log?  
If .ulg try uploading to the new flight review. [http://logs.px4.io/](http://logs.px4.io/)
