wp 3.5.1 works? I have problems

hello i need help, I worked fine before, but I had previous version of wordpress, now I have the latest version (3.51) and can not get it to work.

Before I had my site running in web.portalfoxmix.cl but then i had to change direction and now operates in https://www.portalfoxmix.cl / web might please for this reason does not work.

As much as I seek options, and delete the plugin, I take my old user and there is no case that works.

excuse my bad English I’m Latino
