For some reason, the past few days my site has been taking very long to load. I am not sure what is going on or what to do. I have tried to optimize my database per GoDaddy's recommendation, but that hasnt helped me. It's not only my zencart website that takes forever to load, but the admin side of my site does the same thing. I dont think its a server issue because my wordpress blog on my site works just fine. Can someone help me please?
