This is a total emergency, and I need help!!! I can't find any documentation about this problem on either website... I work for a non-profit organization - and I am a new intern. They put me in charge of updating their website, and I was working on making a photo gallery. I decided to use a Flickr plugin - it's called "Flickr Gallery" by Dan Coulter. I installed that onto my wordpress account, and then the plugin instructions said to type in "Shortcodes" into the content of WordPress pages and posts. I took one of the shortcodes: [flickr-gallery mode="tag" tags="foo"tag_mode="all"] and I put it into the theme functions.php file.
I pressed the update site button.
All of a sudden, EVERYTHING disappeared. I can't access my companys website, I can't change anything in the stylesheets, I can't get on the site from Firefox OR Internet Explorer, and it just says "HTTP Error". I need help... I just need to get back to the stylesheet and delete the shortcode that I put in... it would be so easy if I could just access it... but something is wrong, I feel awful, and I am new at this job and I just deleted their website... what can I do???
I expected the photogallery from Flickr to show up on my front page. I don't know much about wordpress, so I was experimenting to see where it would show up... HELP!!! Please!!!!!
