Hi taimursharif, I noticed your profile and would like to offer you my project. 1- P3 profiler (Activate) to check top used resources because hosting was down because website is using a lot of resources and memory. Let me know if I have to purchase the app.
2- Find and remove all not used website plugins that might make the website slow and use more memory. I believe like store that we are not using and other plugins…
3- Update wordpress and Yoast SEO
4- Install [login to view URL] for faster performance if performance will be better. Let me know if I have to purchase the app or I already have it.
