if (!customErrorsSection.SectionInformation.IsLocked)
{
    // Remove the error at 0 index
    customErrorsCollection.RemoveAt(0);
    configuration.Save();
}

If Not customErrorsSection.SectionInformation.IsLocked Then
   ' Remove the error at 0 index
   customErrorsCollection.RemoveAt(0)

Remarks

The RemoveAt method inserts a remove element into the customErrors section of the configuration file at the current hierarchy level. This is to remove the reference to the add element defined in the parent configuration files at higher-level in the hierarchy.

Note The add elements are not deleted from the parent configuration files. They are merely deactivated. However, the RemoveAt method does actually delete them at the current hierarchy level.
