500 Internal server error, also issue switching from basic to cpanel x3

[matcat9]

I've got the same 500 I've seen in a couple of recent threads. I've been editing the .htaccess in public_html but I haven't been able to fix the problem.
I've also been unable to switch my theme to cpanel x3, I get automatically logged out every time I make an attempt.

Any help is much appreciated, Thanks.

Hi matcat9,

In your .htaccess file, you had a "SetEnv" line causing issues. I've commented out the line for you, and your site is now loading fine.

I've also switched your account over to cPanel x3 manually.

Thank you,

Yep, looks all good.
Thanks heaps, I would never have found the SetEnv line without seeing the error log.
