I recently had an issue when trying to upload multiple documents to SharePoint 2007 Document Library . I receive the following error :” Cannot run Windows SharePoint Services on this page” .
To fix this issue :
1) Go to the Central Administration from Start > Microsoft Office Server à SharePoint Central Administration
2) Choose the Application Management tab
3) Choose Authentication providers from Application Security
4) Change the web Application to your web application then select the zone that failed ( Mine was Default )
5) Disable the client integration by selecting No
6) Return to the default zone again
7) Enable the client integration by choosing “Yes”
8) Now you can use the multiple upload feature
