Hi Christine,
We had the same problem, I could publish the page after removing umbraco.config and recyle app pool! But why this error happens in the first place? how can we avoid this on PRODUCTION SITE?
Quick note just to highlight that I received this error whilst setting up a staging website - 7.6.5, Plesk, FTP copy, database copy, some file permission issues (resolved), App_Data/Cache not copied - and was stumped for a while on this.
Copying over the other site's App_Data moved the error along to a PetaPoco Null Argument Exception but the connection string was fine.
The problem? <add key="umbracoUseSSL" value="true"/> The staging website didn't have an SSL certificate or even a domain attached.
Edit: Sorry should have made it clear - setting <add key="umbracoUseSSL" value="false"/> solved the issue. Deleting Umbraco.config (and\or the App_Data folder) and refreshing the application folder didn't resolve this version of the issue.
@Dan - I've update my original post to make things a little more clear. Just wanted to post to help others in the same predicament. I couldn't run the Health Check as the website didn't progress that far (unless there is an offline way to check); besides which the file was A okay on the Live environment. Thanks.
Wondering if there was ever a solution to this, i'm seeing it a lot on a v7.15.7 site.
Error displayed is 'The Xml cache is corrupt. Use the Health Check data integrity dashboard to fix it.' There is no health check data integrity errors shown and certainly no way to fix it from there.
The only way ive been able to get the sites running is to republish the site from the content section (right click, republish site) which works everytime.
Problem here is that this is happening in a load balanced environment as well as local - load balanced is setup on Azure and we have no access to the front end site, only the admin site (locked down by rewrite rules) so impossible to fix
I've searched through the Umbraco source for those error strings but cannot find them - Just want to try and understand how the error is triggered and work it back from there.
Any suggestions?

today I had the same issue in UAT environment even it was working in DEV environment. Finally it occurred to me that it could be the folder permissions as I deployed the website using CI/CD pipeline by copying all files from build machine. I checked permissions of the root website foder that IIS application is mapped to, compared with DEV one and noticed that there is missing Application Pool identity in the list in UAT. I added it and forced to update on all subfolders and files and it worked right after that!
Based on that I now believe this error message is absolutely unrelated to any XML corruption or cache problem. This is a general error message that can be caused by dozens of reasons!

Back office error:
Hi Christine,
Have you tried deleting and regenerating your Umbraco cache file?
You can find it in:
Once you have deleted it, recycle your AppPool and hit your site again and it should automatically re-create it for you.
Regards
Craig
Hi Christine, did this resolve your issue?
Hi Craig, we deleted and regenerated our Umbraco cache, and the issue came right back. The new cache was corrupted again.
Thank you. Recycling the app pool afterwards was the thing I hadn't done that fixed me having exactly this problem just now.
Thank you! 😊
