A dark overlay appears when Click the delete Action button on the list page in SharePoint 2013. What could be the possible causes and solutions for this issue?

The appearance of a dark overlay when clicking the delete action button in SharePoint 2013 can be caused by several factors. Here are some possible causes and their corresponding solutions:

1. Browser Compatibility Issues: SharePoint 2013 supports various web browsers, but not all browsers may behave the same way when using SharePoint features. The dark overlay issue may occur due to compatibility issues with certain browsers. To resolve this issue, try using a different browser or ensure that your browser is up-to-date with the latest patches and updates.
2. JavaScript and CSS conflicts: SharePoint uses a lot of JavaScript and CSS files to render its pages. Conflicts between these files can cause unexpected behavior, such as the dark overlay issue. To troubleshoot this issue, try disabling JavaScript and CSS files one by one to identify the conflicting file. You can also try using a different version of SharePoint or a different theme to see if the issue persists.
3. Permission issues: If you don't have the necessary permissions to delete items in SharePoint, you may see a dark overlay instead of the expected delete confirmation dialog. To resolve this issue, check your permissions and ensure that you have the necessary delete permissions for the items you are trying to delete.
4. SharePoint Designer Workflow: If you have SharePoint Designer workflows running on your site, they may interfere with the delete action button and cause the dark overlay issue. To resolve this issue, try disabling the workflows temporarily and see if the issue persists. If the issue is caused by a specific workflow, you may need to modify it to allow deletions.
5. Third-party Add-ins: Third-party add-ins can also cause conflicts with SharePoint features, including the delete action button. To identify if a third-party add-in is causing the issue, try disabling them one by one and see if the issue persists. If you identify the add-in causing the issue, you may need to contact the add-in vendor for a resolution.
6. Server-side issues: In some cases, the issue may be caused by server-side issues, such as insufficient memory or processing power. To resolve this issue, you may need to contact your SharePoint administrator or IT department for assistance. They may need to perform server maintenance or upgrade the server hardware to resolve the issue.

In summary, the dark overlay issue when clicking the delete action button in SharePoint 2013 can be caused by various factors, including browser compatibility issues, JavaScript and CSS conflicts, permission issues, SharePoint Designer workflows, third-party add-ins, and server-side issues. To resolve the issue, you may need to try different solutions based on the underlying cause.
