Bug reports can be made through our Github issues page.
Please try to include as much information as possible: JASP version, operating system, what you were doing, the JASP file, or the data file, screenshots, etc.
It’s also worth noting what ‘crash’ means. A crash is where the software suddenly and unexpectedly closes down. If you run an analysis, and it says “An unexpected error occurred” this is not a crash and the specified message can be send to us. Correctly describing an issue will make all of our lives easier!
