Pinboard Theme errors and WP Dashboard not loading!

Hi there,

I am helping a friend with a website and ran into an issue. I was trying to add an Instagram social media icon to the link options under “Theme Options” and added a few lines of code to the functions.php and header.php. I got a few parse errors and a fatal error but it seems I’ve remedied those (or so says my error log). However, now I cannot access the dashboard, the image slider doesn’t load correctly, the caption background box disappeared and the website seems to be in a neverending “loading” stage – I have NO clue how to fix this or how this could have happened. She needs the site up today for her non-profit release presentation.

I have been trying to figure out where the code got messed up and I can’t. I also have re-uploaded things via FTP to see if it would bring things back to the way they were before and it didn’t work. I even went so far as reinstalling the entire theme but then I lost the “theme options” tab on the dashboard.

Any clue what is going on? https://www.seedgrowchange.org

Thank you so much in advance.
