We noticed that one cookie that is saving information when cookies are accepted is in the format DateTime object. Once this cookie is deleted or all cookies are cleared, the site will start working. We tested this also with a simple scenario. Setup one test cookie that is in DateTime object format and we also reproduced the above problem. ADF is only used as a module included in web.config in order to enable the proper work of XPM. On staging ADF is present and on live not, so we tested there above scenario and we could not reproduce the problem. Accepting cookies will not crash that environment.
Wondering if there is some easy solution for this in order to force ADF to accept DateTime object cookies or is this some bug? Is anyone had similar issue?
