I am not able to update my wordpress website

I used wamp to build my website on my computer local host. The website is https://godhanuman.com/
and then I imported all it’s data to my godaddy hosting account where I am hosting this website.

Now whenever I try to update any pages content more than once, it gives me error message. The error is like the website stops updating and it will not update for 15-20 minutes.

I tried to fix this problem by re-uploading the website and wordpress cms but it didn’t fix.

Please help
Thanks
