I visited your website, the website opened without any issues.
I guess that the issue is solved.
Thanks for your help. It was resolved after I restored it to yesterday backup. But it came back again. You can check it now, not working.
Can you please help to resolve this issue permanently?
I tried to open the website again, it still loaded without issues.
However, you might want to clear your cache and check whether or not the issue still exists.
Also, can you confirm that your WordPress and PHP versions are up to date?
Thanks for your effort. It has been resolved . I found out one of the installed plugins was causing the issue.
