Opening elgg on another network

Hi this is probably a very novice question, but I couldn't find a suitable answer by searching. I'm trying to show the webpage I'm designing using elgg as a base to someone on his home network. My solution was to copy the elgg folder from my desktop on to a usb key.


I copied the elgg folder from my usb key to the xamp/htdocs/sites folder along with the data folder. When I'm running xampp and try to open the elgg location ( I get a blank page, and with debug running, the error: Fatal error: Call to undefined function elgg_in_context() in C:\xampp\htdocs\sites\musynapp\elgg-1.8.18\engine\lib\elgglib.php on line 1198.


Is there any quick fix to elgg so that I can open it on any network?
