Hi ,
if it's your defined class try and create a folder where moorexa can autoload all your classes and register it in the autoloader file. Here is where the autoloader can be found : system/inc/autoloader.php. You could also try other possible means, like speak to Joesphi, he could be of help
to you or maybe copy the error you see and ask other moorexa developers on Stack Overflow. Thank
you for building with Moorexa.
