Posted articles are not open properly.

It sounds like you're facing an issue where some of your articles are not opening correctly due to a discrepancy between the new portal and the older portal. This type of problem can occur when there are compatibility issues between the content of the articles and the functionality of the portals.

To resolve this, you may need to investigate the differences between the new and older portals in terms of how they handle article formatting, styles, or any other specific features that could be causing the problem. Here are some steps you can consider:

1. Check Compatibility: Ensure that the articles are formatted in a way that is compatible with both portals. This could involve checking for any HTML or CSS discrepancies that might be affecting how the content is displayed.

2. Portal Settings: Look into the settings of both portals to see if there are any options or configurations that could be impacting how articles are displayed. Adjusting these settings could potentially resolve the issue.

3. Content Migration: If the articles were originally created in the old portal and then transferred to the new one, there may have been issues during the migration process that are causing the problem. Review the migration steps to see if any errors occurred.

4. Version Control: Ensure that both portals are running the latest versions to minimize compatibility issues. Updates often include bug fixes and improvements that could address the problem you are experiencing.
