Website crashed after automatic update

[hans]

Hello, need a bit of help here. My Laytheme-Site for an artist is not working anymore after the last automatic Laytheme-update (from version 9.5.3 to 9.5.6). The URL is https://danielhauptmann.com/

I can login to WordPress via Wiederherstellungsmodus, and it reports the theme as corrupted. Description: There is a style sheet missing.
I had a look into the Laytheme-Folder on the Server and replaced the CSS-File "parsley.css" with a backup-file, but this seems to have no effect.

Have you got any ideas what went wrong and how to proceed?

Best, Hans

hey yes please read this:

your website seems to be online, so you can probably just update lay theme in /wp-admin/ and it should be fine

Hi and thanks for instant feedback, I was able to fix it following your instructions, via FTP upload and renaming the lay theme folder. Everything is fine, so thanks and a great weekend.
