A script on this page is causing Internet Explorer to run slowly: SharePoint 2010


Issue: We have a site collection which was using a JS query and some HTML tags in CEWP. When we browse the sites, it loads fine. The moment we click on Edit page from Site Actions. The page stopped responding and shows an error message:

Error: A script on this page is causing Internet Explorer to run slowly.


Reason for Occurrence: Before going to any resolution we need to understand why this issue occurs. When programmers make mistakes, the computer user is given a choice to continue running the program (script) or not. Since these error notifications are about 99.99% programming related, there's not much you can do. Especially if you upgraded to IE7 by itself or Vista (which has IE7 as the default browser). This could be referred to as a IE related issue.

Resolution: There are many sites on internet which support multiple resolutions such as one below you can try.

1. Open Internet Explorer.

2. On the Tools menu, click Internet Options.

3. In the Internet Options dialog box, click Advanced.

4. Click to select the Disable script debugging check box.

5. Click to clear the Display a notification about every script error check box.

6. Click OK.

However, in my case increasing the script time-out amount in Internet Explorer by modifying a registry entry on specific client computers worked.

The KB Article supports that resolution is: http://support.microsoft.com/kb/175500.

If you have any queries/questions regarding the above mentioned information then please let me know.

I would be more than happy to help you as well as resolves your issues, thank you.

Applies to: SharePoint Foundation Server 2010, SharePoint 2010.
