Umbraco - The Xml cache is corrupt. Use the Health Check data integrity dashboard to fix it

Question

I am getting this error after deploying Umbraco website to the shared hosting site.

Couldn't able to find any solution. Tried refreshing App Pool

The Xml cache is corrupt. Use the Health Check data integrity dashboard to fix it.

Please if anyone can help, I am on production server now. Local is running perfectly fine.

Answer 1

We've had the same issue recur a few times over the last few weeks, with content editors suddenly unable to preview anything.

• "Republish entire site" - doesn't work
• Restarting the site / recycle app pool - doesn't work
• Deleting Umbraco's cache - doesn't work
• umbracoUseSSL is already set correctly

What does work, every time: Empty Umbraco's recycle bin!

Can anyone provide some insight as to why that's a solution, or anything we can do about it? How could the recycle bin's contents even be involved in the previewing functionality?

Edit: the issue we were experiencing was fixed in the 7.15.1 update, as mentioned by Steve Megson here:

There was an issue with preview in 7.15.0 (fixed in 7.15.1) which would throw this exception when it failed to generate the preview version of the XML cache

Answer 2

Are you able to access the URL "/umbraco/dialogs/republish.aspx?xml=true" on your production server?

I've had this happen in the past on earlier versions of Umbraco, and after running this I have been able to go into the backoffice and address the issues with the XML data integrity.

Outside of this, I echo Robert's point on posting on Our.
