Could not load file or assembly

Hi,

I’m looking for a few pointers on how to resolve an issue caused by an upgrade of one of our live sites.  The upgrade was from 2022.1121.302.452 to 2022.2.205.103.4522 and occurred last week.  The symptoms are the same as outlined in the post below except that:

• Issue is ocuring on a Live site not a local install
• Error message relates to Newtonsoft: Could not load file or assembly 'Newtonsoft.Json, Version=13.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The assembly being used in the customisation is Newtonsoft 13.0.3.  In the WebConfig file on the local instance which doesn’t throw this error there is:

The customisation on the local site works fine despite the version being outside 13.0.03 being outside the range.  I don’t know how or if you can change the web.config file on a live site.

Maybe this is something that only support can resolve?

Thanks in advance for any help,

John.
