Has to be said I don't often look in here but having done so after the update from 1.24.1 to 1.24.2 Backdrop is flagging some pages as missing.
Based on the URL quoted it appears to be reference to an old page from the Bolt website before I moved the site to Backdrop. I assume that it is a link that hasn't been updated.
I did a search on the site for "newsitem" which is part of the url but nothing came up. Is there a simple way I can find it?
