I'm getting an unexpected error when trying to modify a landing page using Site Management Tools

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you might be encountering an issue with your role permissions or the settings of your landing page. Here are a few steps you can take to troubleshoot: 1. Check your role permissions: Make sure that your role has the necessary permissions to modify the landing page. If you're unsure, you can check with your Administrator. 2. Verify the landing page settings: If you're trying to set a landing page in the preferences of Vendor Center Roles and it's not working, it could be due to the settings of the landing page itself. Make sure the landing page is active and properly configured. 3. Enable Vendor Access: If you're working with the Vendor Center, you might need to enable Vendor Access. You can do this by going to Setup > Company > Setup Tasks > Enable Features. Click the Web Presence subtab and check the Vendor Access box. 4. Check the associated script: If you're getting an error when trying to edit a plugin, it might be due to an issue with the associated script. You might want to open the script and check what's going on, particularly with the page_unload function. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
