Hi, I have sharepoint site that users can see it through internet.some of users(they aren’t join to our domain) report that they can’t attach file, when I check sharepoint site in my office(my pc join to domain)there is no problem and I can attach file.but when I check this site in my home and through internet I can’t attach file too!and see java error : " Document.getElementById(…)’ is null or not an object Form.js” How this is possible and what is wrong? Also I know anonymous user can’t attach file and me and our users have this problem even we are enter site and authenticated! I’m very appreciated if anyone can help me. Thanx.

Where do you get this error ? are you getting in IE status bar at left side ? Are you trying to attach the file into the list item? or uploading a document into document library? please elaborate, also let me know what version of IE are you using (office and home).Thanks, Arun, Posting is provided "AS IS" with no warranties, and confers no rights.

Hi Arunraj, Yes I getting this error in IE status bar at left down side. And when I try to attach file into list item I get this error. I use IE version 8 both in office & home.

Did you try to upload any document to a document library from your home computer ? Please check this and let me know if you are facing the same issue with uploading document as well, also you can try click on any dorp down option on your site and let me know if you get the same message.Thanks, Arun, Posting is provided "AS IS" with no warranties, and confers no rights.

When I try to upload a document to Document Library, this pop up side bar appears:” This website wants to run the following add-in: ‘Microsoft Office Multiple Upload’ from ‘Microsoft Corporation’. If you trust the website and the add-on and want to allow it to run,click here” I don’t click on “Run Add-on” pop up , but I can upload word document,next time I try to upload document,when I see this pop up, I click on Run Add-on on all website, then return to my list and try to attach file. This time is work J But our all users have to do same thing that I do?!!! Or after this settings that I do, the user don’t need to do it again on their pc?!! And what is solution for my other Internet sharepoint site? I have to do this settings for all of them?!! It’s really difficult !

Users has to Run this "Add-on" once in their local PC when it asks and then this functionality will start work for all the SharePoint sites, they don't need to do the same steps for all the SharePoint sites again. Please instruct the users to do so. OR Also ask the users to add your SharePoint sites into Trusted sites in their home pc. This will resolve the issue. 1.Open Internet Explorer. 2.Goto the Tools menu, click Internet Options, and then click the Security tab. 3.Click Trusted sites, and then click Sites. 4.In the Trusted sites dialog box, type the URL of the SharePoint site in the Add this website to the zone box, and then click Add. 5.Click Close, and then click OK. Now , close your Internet Explorer and try to open the site again and try attach/upload the file.Thanks, Arun, Posting is provided "AS IS" with no warranties, and confers no rights.

Thanx Arunraj For your helpful answer. I give this instruction to our users, and their problem solved.
