All I was doing to the site was converting it multi-tennant which which in turn required a change in my SiteLayoutController to indicate the site root now started at the second level in the tree.
The change was tested locally ok but when I deployed to my live environment I started seeing the following error:

I don't use MySQL and I didn't update any NuGet packages as part of the changes so not sure why this started happening. The only way I was able to resolve it was to add the following in the <dependentAssembly> section of the web.config:
<dependentAssembly>
<assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.9.10.0" newVersion="6.9.10.0" />
</dependentAssembly>

I then tried to recreate the issue by removing the entry above and recycling the Application Pool... it loaded ok without the reference. Not sure why the blip occurred but i'm back up and working again!
