Moving Expression Engine web site issue

I had a website running on expressionengine. We developed a new site in Wordpress. We backed up the EE site with the DB and replaced it with the WP site. 

Now we want to move the EE site to a new URL, to keep it as archives. The former site was hosted with Bluehost but I want to migrate it to Wiredtree.

I followed all the instructions mentioned here to transfer the EE site: https://docs.expressionengine.com/latest/operations/moving.html.

Most of it works, I can have access to the site, the theme is working, the back-end is working (except for the modules pages). And the content doesn't appear on the website as you can see here: http://tempcammac.ca/index.php

When I go in the dashboard, everything works, but when i try to access the modules page, I get a white screen? Is it a problem with the memory_limit from the server? How can I fix it?
