Error with selecting image in Kentico Admin

Francis Carroll asked on May 5, 2023 12:31


I am runninbg Kentio v13.0.101 using MVC5 and IIS10.

I am having an issue on our site where when we select an image/navigate in the media library from the Pages application it causes an error to occur and on refresh kicks the user out of the admin.

Here is the log that pops up in the admin:

Event ID:31144
Event type:Error

Try accessing both the cms and mvc site with HTTPS or HTTP in the browser window.

If that doesn't fix it, try clearing your cookies and doing a hard refresh in the Admin.

We have tried that and that didnt help, i also tried resigning the macros to see if that would help and we still cant navigate through the media library without the admin throwing the above error and kicking the user out of the admin.
