If a Web Application encounters an error while attempting to enumerate existing BLOB cache values set by Nauplius.SharePoint.BlobCache while loading the BLOB Cache settings page, run the following PowerShell cmdlets:
$wa = Get-SPWebApplication http://webAppUrl
$modifications = $wa.WebConfigModifications | where {$_.Owner -eq "Nauplius.SharePoint.BlobCache"}
foreach ($modification in $modifications)
{$wa.WebConfigModifications.Remove($modification)}
$wa.Update()
$wa.Parent.ApplyWebConfigModifications()
This will remove all BLOB Cache settings set by this solution, but will resolve the error when attempting to load the BLOB Cache settings page.
