Fixing broken APIs

The following APIs were already integrated and working, due to migration and change of domain and loss of some files they have partially stopped working, in a CodeIgniter project

Stripe Connect: working except split payment
Zoom: partially working
Forum (Tecdiary): working, needs assigning different login to different users
LiveChat (Mirrormx): not working
Signiturit: not working

these fixes need to be done remotely through TeamViewer.
