openatrium installation error?
You might need to do a change in my.ini file which is configuration file for your mysql server.

Change


open the my.ini file.
you might not have this (max_allowed_packet) line already there.
So you need to add this line at some point in this file.

max_allowed_packet=24M
Save the file
Restart mysql server.
