Page with garbled text appears when any unhandled error occurs

Question

Whenever an unhandled error occurs, I get following screen instead of yellow screen.

Please note I have enabled Localization in ASP.NET Boilerplate and current language/culture is set to en-US.

For some pages, the language text values are stored in AbpLanguageTexts table.

Answer 1

This is happens when the page is send back with gZip compression but with wrong Content-Length.

The result are the non-correct decompress of the data.

The solution is to remove the Content-Length or remove the compression from the error page/message.
