Apache/Drupal: Drupal website with links wrongly pointing to another Drupal site

Question

At my job we have Apache installed in an Ubuntu 16.04 lts server, the folder where the websites are is /var/www/html

We have a Drupal website in /var/www/html/version1 . The problem is that after copying the folder of the site and naming it /var/www/html/version2 to do some testing, we deleted /var/www/html/version2 and when going to localhost:8080/version1/ the links in that site inexplicably pointed to version2 ie localhost:8080/version2/news

That was yesterday, today the links are pointing correctly to localhost:8080/version1/news but If I access from a public ip that is opened, ie [public_ip]:8080/version1/ and click the links of the news it redirects to [public_ip]:8080/version2/news and obviously it gives page not found. If I go to [public_ip]:8080/version1/news directly it access it without any problem.

Where is the problem? I can provide the configuration files from apache or the sites. I appreciate any help!

In the end, the problem was on Drupal, According to what they say here https://www.drupal.org/node/845026 Drupal does not save html files, it generates them 'on the fly' by consulting a database.

So to update the links you have to clean the cache of Drupal

The problem was solved by the Drupal administrator simply by login in the admin panel.
