Connecting shopify to wordpress gives 404 error on root WP pages

Hello all,

I have been online with both, Namecheap, (my 3rd party host) and Shopify for hours to no avail on this issue. I am hoping someone here will be able to share some insight.

My shop url is kolibrico.art I am running the Debut theme on Shopify.

I am using avada on wordpress which is hosted by a 3rd party host.

WHAT I AM TRYING TO DO:

I want users who come to kolibrico.art or www.kolibrico.art to see my shopify store. The nav at the top has links to my about us page and I want them to be functional.

WHAT BROKE :

I created a sub domain boutique.kolibrico.art and linked my shopify store to it.

I connected kolibrico.art and www.kolibrico.art to Shopify and that works nicely.

However, right after connecting my domain, I stopped having access to my wordpress admin and any link that is pointed to root, such as my about us page gives me a 404.

THE BIG PROBLEM :

3rd party host says this is a shopify problem. Shopify says this is a wordpress problem. Have you had this problem?

Things I have tried that don’t work

  1. Since WP is installed on root, I reverted the A Record IP address back to my hosting company, but still no wp admin.
  2. I have updated the .htaccess file.
  3. Waited hours for propagation
  4. Modified the config file
  5. Cleared cache and cookies
  6. disabled plugins
  7. Spoke with tech support at Namecheap and Shopify
  8. Have not modified the shopify code.
  9. Have not installed apps.

Any ideas on what I could try next?

I basically want to keep wordpress because I like the layout of my about us page on WP and Shopify’s page creator is pretty basic. I don’t think I can reproduce it.

Thanks for your help! Ready to make this work.
