My site was fine last month, not sure if the upgrade to 3.13 this week changed anything but it's ridiculously slow. Especially the portfolio page http://zumoarts.com/portfolio. I am running a 3rd party theme, but again, it was working fine and fast a few weeks ago.
I have deactivated all plug-ins that I don't need.
Can someone please check my site and let me know what to do? Thanks!
