I have updated my WordPress to 5.7, than updated all the plugins. It worked all fine.
Finally I updated Highend theme from version 3.6.12 to 3.7.3.
By doing so, I lost access to the website: the website does not open or refresh (although the admin console is still working).
Fortunately, I have restored my backup. Any idea where this could come from?
Thanks and regards
