I have 2 Themes installed in my webpage: SimploBlack and Rockwell (I downloaded both from http://www.site5.com/). In the last 2 weeks i have been using the "rockwell" theme. Suddenly, yesterdey, it just stopped working: Picture of the "rockwell" theme today. I deleted all the files of that theme and download it again, but it didn't solve the problem. I changed the theme to "smploblack" and it works properly: Picture of the "simpoblack" theme. I would like to keep using the "rockwell" theme, does anybody know how can I solve my problem?
PD: Before it crashed, I published 2 posts, create a new page (contact page) and installed and activated a plugin (Contact Form 7). After re-downloading and re-uploading the rockwell theme I deleted the page and desactivated the plugin, just in case, but nothing happened. Anyway, all works properly with "sipmobalck" theme. My webpage is edmw.com.ar.
