Hi everyone. I upgraded our website from version 12 to 15 by skipping the intermediate versions. Everything seems to work fine when I publish content, but I keep getting this error that no one on my team can solve. We suspect it might be due to an improper upgrade. Does anyone have any suggestions? Should we revert and upgrade step by step, or is there another solution? https://cdn.discordapp.com/attachments/1349317609824456724/1349317610323316736/Screenshot_2025-03-12_104143.png?ex=67d2a973&is=67d157f3&hm=88375383d2d3412833359913cac3aa65e364dfd777bd6b3bab3dc31fc22f43e9&

Hi @Neuro, just to let you know that we'll soon stop the ability to create new questions on Discord as we're moving the ⁠help-with-umbraco channel over to our new forum. You can read more about this initiative here: ⁠social⁠ I'd recommend you log in to the forum (https://forum.umbraco.com/) with your GitHub account and post this question there. Thanks, and see you there!
