We have a SharePoint 2010 site collection in which except the home page all other pages are working normally. When we try to click on 'Add a Web Part' button on the home page we won't get the web part gallery and hence we are unable to add any web parts on the home page.
We checked the permissions, it is fine I have web application level full control.
Home page is not checkout to any body. All other site collections have good home pages where we are able to add web parts.
Please let me know how to fix this issue.
Thank you,
smith
