parse error, no orig to re-load, can I get in

Do you have FTP access to your site?

I do not, nor do I know how to. I’m in the learning process which is how I screwed up the functions file in the first place. Made no back-up before making changes. Original theme files, which I paid for, are missing from my computer. Is there a way to get onto the admin site & uninstall it?

OR, is there a way to get the original theme files re-downloaded to my computer, since I did buy them (in June)? No idea why they are missing, but they are.

Ask the people you bought the theme from.

WordPress. How do I ask them?

I’m sorry but as you are using a commercial theme, you need to seek support from the theme’s developer/vendor. We do not support commercial products here.
