Enough problems for everyone

Error messages everywhere. Visitors cannot register or log in.

I did the automatic install on Bluehost. I then changed the theme to Cutline, with 3 columns. Since then everything has gone haywire.

I seem to have assumed that the installation used my given name for the username (crawford). It didn’t. I ended up with the username for the host being one thing (crawfos2) and the one for WordPress being another. I tried to give it the same username as the host and delete the other. WP will not permit deletion of the first username it accepted. It did allow me to delete the second username. The first could not be changed to Editor or Author. It remained Administrator. This may be one of my problems, or it may not be.

Going to my blog http://www.crawfordharris.com a visitor will see –
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home1/crawfos2/public_html/wp-includes/widgets.php on line 60 – at the very top, above my blog. The code to which it refers is – $sidebar = array_merge($defaults, $args);
I don’t know enough about the coding to know if that is correct or not.

Trying to log in, a visitor will be met with –
Warning: Cannot modify header information – headers already sent by (output started at /home1/crawfos2/public_html/wp-includes/widgets.php:60) in /home1/crawfos2/public_html/wp-login.php on line 202 – the code referred to is – $action = ‘resetpass’;

The visitor also gets the following –
Warning: Cannot modify header information – headers already sent by (output started at /home1/crawfos2/public_html/wp-includes/widgets.php:60) in /home1/crawfos2/public_html/wp-login.php on line 214 – referring to this code – update_option(‘siteurl’, dirname($schema . $_SERVER[‘HTTP_HOST’] . $_SERVER[‘PHP_SELF’]) );

There’s more to greet the visitor –
Warning: Cannot modify header information – headers already sent by (output started at /home1/crawfos2/public_html/wp-includes/widgets.php:60) in /home1/crawfos2/public_html/wp-includes/pluggable.php on line 557 – and –

Is it any wonder that someone barely conversant in HTML is at a complete loss?

There are more problem, such as widgets that are listed but don’t show up on the page and a sitemap that sends one to 404 page.

Please, someone, help this poor lost soul with one or more of these problems.
