Hi Nikko,
Thanks for your reply. I followed your suggestion and installed Envato Market plugin and it did upload the latest version (4.9) of Enfold with an ”update” notice. I attempted to update, but the update failed. The error message said it was because the server timed out. As a result the entire site stopped working – nothing but a blank page when viewing the site URL.

I fixed the site by:
– renaming the new version of Enfold (extracted Enfold folder) that I downloaded from Envato to Enfold-new
– manually uploading this folder to the server via FTP
– renaming the original Enfold folder on the server to Enfold-old
– renaming the new uploaded Enfold-new folder to Enfold
– deleting the Enfold-old folder

The site then started working again. I haven’t detected any problems with it so far.
Regards, ljenk
