Hello,
I’m sorry that things are going slowly for you…As a starting point, can you try running through some of the steps outlined here to see if anything there makes a difference? With performance issues, it is likely that it is not just one thing that is causing the issues, but rather a combination of things – so, it might take a few changes to see an improvement.
After following the steps, I would also recommend trying out the free Query Monitor plugin, which will tell you if there are any slow queries on a particular page. If you see any, can you please copy/paste the info into your reply so that we can take a look?
Can you please share your system info with me as well?
Thanks,
Jennifer
