I login the website after 2-3 days and today i noticed that website is taking a lot of loading time even when a user opens any pages fron front end or even if i need to go to any widget it takes a lot of time to open that. I confirmed and connected with the server support and they mentioned that the some plugins are bugging. Kindly have a look and resolve it asap.
If you think you need to downgrade or upgrade wordpress versions kindly do whatever needed at your end
