Problems with copying my site to test site
Hi,
before upgrading my site to 5.3, I would like to do a test in my test directory.
My live site is mysite.sub.xx and my test site is server.sub.xx/testdrupal
I did the copy of my live site to the test directory, the .htaccess also.
I did the copy of the DB of my livesite to a new DB called testdrupal.
I modified in setting.php $db_url and $base_url.
My testdrupal version shows now the welcome page. But if I click on any link, I have an Error page (Object not found).
In the testdrupal DB, I cleaned all the rows from cache table.
I cleaned also the cache of my browser.
But I still have error when clicking on a link of my welcome page.
By the way the welcome page says:
Welcome to your new Drupal website!
Please follow these steps to set up and start using your website: ....
What should I do?

Start New Site
I am still struggling with total breakage from an upgrade from 4.7 -> 5.3 and mad as hell about it.
I would avoid touching production and start a new site, new DB. Then export the old data and import it into the new mysql DB.
Learn from my horrible miscalculations.
