I was hacked last week and did a back up form before the hack. I have since updated to the latest version. Since then I can log in, and all my content is there, but my site is a white plank page when I try to view. The site is jonesautoinc.com/rebuilders

Thanks is advance for your help.

Maybe you have not totally cleared out the hack. Most likely source of the problem would be the .htaccess file, but it could be something else.

Also check your CGI error logs as they might have a clue.

I have been hacked last week, check with original provider file manager the .htaccess file, (it is not in html space)

now I see this:
Fatal error: Cannot redeclare zenjavascript() (previously declared in /home6/tysonkni/public_html/jonesautoinc/rebuilders/zp-core/template-functions.php:82) in /home6/tysonkni/public_html/jonesautoinc/rebuilders/zp-core/zp-extensions/deprecated-functions.php on line 414

now it says this:
Fatal error: Cannot redeclare zenjavascript() (previously declared in /home6/tysonkni/public_html/jonesautoinc/rebuilders/zp-core/template-functions.php:82) in /home6/tysonkni/public_html/jonesautoinc/rebuilders/zp-core/zp-extensions/deprecated-functions.php on line 414
