I have a bunch of pages that I or other content editors have added Web Parts to via the Design tab in the Pages app. The Web Parts appear to function correctly when I view the page.
Every so often I get a note from a content editor that they are seeing stale content on the page. Sure enough, when I log into the CMS and go to the pages app and view the Page preview tab, I see old content. I then go to the Design tab and edit the Web Part they are looking at, I do see their new content appear in the Web Part form controls. Very strange. I have not set up any caching on the page, or these Web Parts.
After poking around a bit, I found the "Edit Regions & Web Parts" under the General tab in the Pages app. It's beneath an "Advanced" label. I open this up and I see a window labeled "Editable content" showing two lists "Editable web parts" and "Editable regions". Everytime a content editor has shown me examples of this stale content, there is an item listed under "Editable web parts", and when I open up that item, it has the "stale" content that the editor is complaining about. It seems to override whatever content is actually assigned to the Web Part in the Design tab. I delete the item from the list, and the page suddenly shows the correct content again.
How is this "Editable web parts" list controlled in Kentico?. What actions create items in this list?
I have hundreds of pages in the site, all of them filled with many Web Parts. But only a handful (less than ten) of pages have been reported with this behavior.
As far as I am aware, all of my content editors are following the same procedure to add these Web Parts to the page using the Design view. Nobody is doing anything differently, or manually creating items in the Editable Web Parts list via that Advanced area.
We've guessed that this may be happening when multiple editors are editing the same piece of content, as we tend to notice the stale entry after a bunch of editors have been active in the system. It's a subjective guess though - all attempts to re-create the issue with multiple editors working at the same time on the same Web Parts have not been able to successfully recreate an item in the list.
Also not sure if it matters, but I am only getting reports of this happening on a single Web Part -- a custom sub-class of the Kentico WYSIWYG editor. This may not be related, but I figured it's something that might be a clue. It's also the most-used Web Part we're utilizing, so it may just be statistics that it's the one we've noticed.
Any ideas on where to start looking? Thanks!
Running Kentico version 11.
