Regardless whether you are using Kalium parent theme or child theme, demo content can be imported into both types.
After that either click Laborator > Demo Content Install from admin menu or Kalium > Demo Content
Then choose from any of demo content packages and click “Install Content Pack”:
A popup will appear for you to choose available content parts you want to import from that content package:
If everything goes fine, then you should see a happy smiley at the end of the process and everything is set up properly:
However, not always things flow as we expect and boom… the unexpected happens and errors during demo content import appear on screen (there may be one or more errors, worst case is all at once):
In this case, don’t panic, but please read this article carefully Recommended PHP configuration limits, and see if you need to increase your PHP limits on your server too.
If encountered this problem and now you increased your PHP limits then please reset your WordPress installation by using this plugin WordPress Reset (By Aristeides Stathopoulos, Matt Martz), then activate the theme and try to install demo-content again. Note that if you use the plugin it will delete pages that you have created earlier on your WordPress site.
If you still can’t install the demo content then we suggest you contact our support for more troubleshooting by our professional support members.
