Hi there, 

I am trying to install Klaviyo on WooCommerce. I have installed the app and trying to connect accounts.

When I go to connect accounts, it displays a 404 error page.

Here is the link URL on the ‘Connect Account’ button:
https://www.klaviyo.com/integration-oauth-one/woocommerce/auth/handle?url=https://development.brstdev.com/klaviyo

Here is the actual URL when clicked:

https://development.brstdev.com/klaviyo/wc-auth/v1/authorize?app_name=Klaviyo&user_id=Y25GtF_WdDNXc&scope=read_write&callback_url=https%3A%2F%2Fwww.klaviyo.com%2Fintegration-oauth-one%2Fwoocommerce%2Fauth%2Fsave%3Fdomain_url%3Dhttps%253A%252F%252Fdevelopment.brstdev.com%252Fklaviyo%252F%26timestamp%3D1662445386&return_url=https%3A%2F%2Fwww.klaviyo.com%2Fintegration%2Fwoocommerce%3Fauth_redirect%3DTrue%26domain_url%3Dhttps%253A%252F%252Fdevelopment.brstdev.com%252Fklaviyo%252F
