I'm getting weird error with publishing pages and form digest. When publishing page is in Published state __REQUESTDIGEST hidden field value is "InvalidFormDigest". I also have Notes web part on this page. So this invalid digest value doesn't let me and any user to submit comments. I enabled verbose logging for social data and found the following error in logs:
argument:<Item type='Add'><Title>test1</Title><RTEContents>dwd</RTEContents></Item> ,message:The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again. ,request:<Item type='Add'><Title>test1</Title><RTEContents>test</RTEContents></Item>
Does anyone know why this might happen and how to troubleshoot __REQUESTDIGEST issues?
Thank you in advance.
