500 Error on member.php

When a user tries to login, they get a 500 error. Not sure when this error started occurring. I've looked at my error logs and see this:


PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent (output started at /home/nightli6/public_html/artoftravelblogging/amember/member.php:8) in /home/nightli6/public_html/artoftravelblogging/amember/common.inc.php on line 1827

This is the page that stopped working: http://artoftravelblogging.com/amember/member.php

Thanks for the help!

Also seeing errors on random sections on aMember like:
WARNING: Illegal string offset 'size' in line 91 of file setup.php

I'm running 3.2.4.

PHP version5.4.8

Read through the forums a bit and did the following but did not resolve it:

- Shut off display_errors in php.ini

- Changed error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE

- a. Edit /amember/common.inc.php and remove this line:
set_magic_quotes_runtime(0);
b. Edit /amember/config.inc.php and add this line to the top of the file:
ini_set("session.save_path", dirname(__FILE__)."/data");

Thanks for quickly replying. I've redirected member.php for now so it didn't confuse others as it still doesnt work. Here's what I have in the first few lines on member.php.

Code:

Thank you again for helping out.
