opencart 2.2.0.0 view the orders, show "error and undefined"

First of all, I think is cross domain problem.

but I'm not sure right now.

anyone know how to fix it.

Check your base url



all depends on your base url :

with or without www
with or without https


then update your .htaccess , use 301 point to default base url .

100% works.

Hi, how do u fixed ?
