Hi,

I recently started having an issue which I think may be related to some of the caching options in Kentico.

When I edit a page, either the template itself or the page content, the system will sometimes revert the page to a previous version of the template. This issue happens intermittently, sometimes the page will look fine for 5-10 minutes while I’m working on it, then revert back to a previous template. If I’ve made a few changes each time I refresh I will get a different version of the changes, almost like Kentico is cycling through the versions of the page.

I noticed this happening after I changed the caching settings, so I reverted to the default caching settings, but I still have the issue. The only other thing I can think of is that we doubled the server’s RAM. I’ve also disabled caching in my browser, so client-side caching shouldn’t be an issue, and this issue happens on more than just my computer, leading me to believe it’s a server-side problem.

I’ve attached a few screenshots showing the issue.
Image 1: This is what the page should look like based on my editing.


Image 2: This is what shows up after I was finished working on the page, saved my changes, and hit refresh a few times on the live site. (This was a previous version of the page)


If I continue to refresh the page I randomly get either Image 1 or Image 2, sometimes it will show the same page for 20+ refreshes, sometimes it switches every refresh. I can’t seem to find any rhyme or reason for this…

Below is the export of my caching settings. They should just be the default settings.

Has anyone else ever experienced an issue like this?

Thanks!
