thank you for this theme, I’m really happy with it.
Although, I tried update my child theme several time (using the plugin you suggested) but it can’t complete the uploading and gives me the 500 Internal Server Error.
Can it be related to the theme or is it due to the hosting?
Thank you for choosing our theme and contacting us.
500 error code says about some internal issue on the server. Maybe it can’t upload the theme because of its size or something like that. Anyway, you need to ask your hosting providers why you get this error. Or you can try to upload the theme folder manually using some FTP client.
