On the older 2.0 versions of CS Cart I was able to put include files. I would like to insert some custom includes but I dont see includes being used in 3.0 so wondering if this is still possible since now it has locations instead.
Are you talking about PHP include() functions or Smarty Template {include file=“foo”} variables?
Both are supported in V3 so not sure exactly what you're asking or wanting to do. An example of what you did (version reference too) would help so we can advise on what to do.
