"Error loading lookups" - Newtonsoft.Json.JsonReaderException due to Gallery site down

[UlyssesWu]

BlogEngine.NET/BlogEngine/BlogEngine.Core/Services/Packaging/Gallery.cs

Lines 74 to 92 in 11b9f17

	/// <summary>
	/// Gets extra filds from remote gallery if gallery supports it
	/// </summary>
	/// <param name="id">Package ID</param>
	/// <returns>Object with extra package fields</returns>
	public static PackageExtra GetPackageExtra(string id)
	{
	try
	{
	var url = BlogConfig.GalleryFeedUrl.Replace("/nuget", "/api/extras/" + id);
	WebClient wc = new WebClient();
	string json = wc.DownloadString(url);
	return JsonConvert.DeserializeObject<PackageExtra>(json);
	}
	catch (Exception)
	{
	return null;
	}
	}

Sadly, the url http://dnbe.net/v01/nuget is down.
Therefore, JsonConvert.DeserializeObject throws a Newtonsoft.Json.JsonReaderException, and causes an Error loading lookups (GET /api/lookups returns 502), makes the whole blog unstable - e.g. Unable to load and change settings, unable to set categories for a new blog post etc.

My solution is removing all 3rd party themes in Custom\Themes. Just keep RazorHost and Standard themes.
I have no idea if you'll still fix this, but this is a serious problem and I should leave my solution here for other users.

I was able to recover some themes through the Internet Archive https://web.archive.org/web/20210701014032/https://archive.codeplex.com/?p=blogenginethemes

The archive Blogenginethemes.zip itself contains an zipfile on the following location releases\0\97f8f351-45d7-4358-b51b-ba6c9d32339a. This zipfile contains several themes, some of them are working on v3.3.8.0, some might require a little change in the site.master, some of them got some little CSS issues.

The following themes are quite OK (might have some minor issues)
