: How to debug an unwanted subdomain redirect? I am trying to switch a dated Magento site in the domain root of a website I am developing (example.com) with a WordPress site located at beta.example.com.

Posted in: #Magento #Redirects #Subdomain #Wordpress

I am trying to switch a dated Magento site in the domain root of a website I am developing (example.com) with a WordPress site located at beta.example.com. First, I want to move the Magento site to legacy.example.com in case visitors need to access it later. I simply copied all the folders from the root directory to the legacy subdomain directory.

However, when I visit legacy.example.com, it redirects me to example.com immediately. If I visit any Magento page on the legacy subdomain it redirects me to example.com (the default index) as well. However, if I visit an independent HTML page that I made such as legacy.example.com/index.html the subdomain does not redirect.

I looked at the .htaccess file located in the main directory for example.com (I copied it to the legacy subdomain along with all the other Magento files) but I can't figure out what exactly is causing the redirect.

How can I find out what exactly is causing the redirect here? The WordPress site located at beta.example.comdoes not have any redirect issues. What is the problem with the Magento site?

UPDATE:

Deleting the entire .htaccess file in the legacy subdomain does not affect the redirect. Is it possible that index.php redirects? I couldn't find a redirect myself in the code shown below:
