I'm having issues regarding My Settings page in Epi. This page seems to be working normally but after some time it starts throwing exceptions (500). After restarting application pool in IIS it again works correctly but after some time it crashes again.

Below is exception:

Here is my web.config localization section:

<localization fallbackBehavior="Echo, MissingMessage, FallbackCulture" fallbackCulture="en">
   <providers>
      <add virtualPath="~/LanguageFiles" name="languageFiles" type="EPiServer.Framework.Localization.XmlResources.FileXmlLocalizationProvider, EPiServer.Framework.AspNet" />
   </providers>
</localization>

Do you have custom admin plugin, from the xml doc

    /// To translate <b>DisplayName</b> and <b>Description</b> of a plug-in you have to add
    /// your own xml file in the �lang/� directory and set the property LanguagePath.
    /// If you for example set LanguagePath to /myplugin/sample the xml paths you add should
    /// be /myplugin/sample/displayname and /myplugin/sample/description.

It's a standard My Settings page when you can for example change UI language. I don't think I need anything special for this to work.

I am able to reproduce this if I change LocalizationService.Current.FallbackBehavior to anything other than FallbackBehaviors.Echo or FallbackBehaviors.Null.
This happens because the "Display Options" plugin (EPiServer.UI.Edit.UserGuiSettings) has no description.

Do you change the value of LocalizationService.Current.FallbackBehavior anywhere in your code?

yes I found something like that:
_localizationService.FallbackBehavior = FallbackBehaviors.FallbackCulture;
_localizationService.FallbackCulture = new CultureInfo("en");

I will try to remove it and we will see if that helps. Thank you for the hint.
