I installed version 3.7.1 on my site. I tried editing the theme code on my site's back end. After saving changes, the site went blank at both the front and back end. I then restored a pasted copy of the original code which I had saved before the modification. But still the front and back end are still blank. I have refreshed a 100times without any changes. I have launching the site through other browsers but the result is the same.
I tried following some of the suggestions in teh forum but I couldn't open up the .htaccess file located in my /public_html folder. How do I modify a file that doesn't open?
