Reproduction Steps:

1. Set up and start a portal

2. Go to Control Panel --> Sites and create 2 sites with the following names: Site1 and Site2

3. Create a page on Site1 called: Page1

4. Create a page on Site2 called Page2

5. In Site1: Go to Content --> Web content and create a basic web content: switch to source view and copy the below content:

<p><a href="http://localhost:8080/web/site1">link to site1</a></p>

<p><a href="http://localhost:8080/web/site2">link to site2</a></p>

<p><a href="http://localhost:8080/web/site1/page1">link to site1 - page1</a></p>

<p><a href="http://localhost:8080/web/site2/page2">link to site2 - page2</a></p>

6. Add a Web Content Display Portlet to Site1, Page1 page and select the web content

7. In Site2: go to Content --> Web Content and Create a basic web content, switch to source view and copy the below content:

<p><a href="http://localhost:8080/web/site1">link to site1</a></p>

<p><a href="http://localhost:8080/web/site2">link to site2</a></p>

<p><a href="http://localhost:8080/web/site1/page1">link to site1 - page1</a></p>

<p><a href="http://localhost:8080/web/site2/page2">link to site2 - page2</a></p>

8. Add a WCD portlet to Site2, Page2 page and select the web content

9. Export both Site1 and Site2 by going to Publishing --> Export

10. Clean the environment (or delete Site1 and Site2)

11. Create Site1 and Site2 again as empty sites

12. Try to import the LAR file of Site1

Actual Result: The import fails with the error:

The file Public_Pages-20200117110747640 (1).lar cannot be imported.
 There are missing references that could not be found in the current site. Please import the following elements first:
 Page: Page2(Referenced by a Web Content Article: test)

Expected Result:

• The LAR file of Site1 of can be successfully imported (despite of containing missing references).
• The LAR file of Site2 can be imported
• All URL references inside the web contents remain correct
