Hi,
I decided to clone my site so that I could get used to Gutenberg before going live with it.
So I now have my active site at https://thecatholictravelguide.com/ that uses 5.1 but with the classic editor with gp premium 1.7.6 and then my cloned site at https://www.thecatholictravelguidecom.lightningbasehosted.com/blog/
All is well on my active site, but on my cloned site it says I have an update to GP premium to 1.7.6, when I try to update this is the message I get:
Update Failed: <!DOCTYPE html> 503 Service Unavailable
503 Service Unavailable
The server is temporarily busy, try again later!
Have gotyten this message several times so wonder what I might be doing wrong.
