This started with ISPConfig 2 back in January and has continued on through the latest upgrade (3.1). It's done it three times this morning and I'm all but ready to call it quits unless someone can point me in the right direction. Whenever I make a change to the anything involving my sites (activating/deactivating, adding SSL, adding a new site), my group file is basically emptied and consequently all of my services on Apache go down. Once I restore the group file, it works well until I have to make another change. It's been a 50-50 proposition since January but in the last five days (since the upgrade to 3.1), it's been more 95-5 that it will happen. Does anyone have an idea what might be the issue here? It's ISPConfig 3.1 on an upgraded Debian 7 box.
