Website is broken when logged out! Please help

Actually, it looks like you removed the CSS file all together. A quick search of the website source shows no reference to a theme CSS file at all?

When I check my FTP I am seeing a .CSS file there though.

And I thought that reinstalling the theme would have taken care of an issue like that, but maybe I’m wrong. Do you have any idea what a potential solution might be?

Which theme is it?

I switched to a different theme to see if that would shed more light and it seems like that different themes CSS is working. When I switched back to my preferred theme I got this warning:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘woocommerce_price_filter_init’ was given in /home/pipeguys/public_html/wp-includes/plugin.php on line 406

Warning: Cannot modify header information – headers already sent by (output started at /home/pipeguys/public_html/wp-includes/plugin.php:406) in /home/pipeguys/public_html/wp-includes/pluggable.php on line 876

the theme is “Forte”

but I am using a child theme

Switch to the original theme and see whether the issue persists.

The theme ‘header’ or ‘function’ file should be calling to the CSS file to include it when loaded. What theme are you using?

I am using theme “forte”

could these warnings be the issue?

so I have done a bit more research and it looks like my theme header.php has a closing </head> after the wp_head(); which is supposed to call my CSS

However, when I look at the source code that </head> tag is not there
