Hmm, looks like your theme is trying to access a function that does not exist. What version of WordPress are you running?
Do you have FTP access to your site? Go to wp-content/themes and delete the folder of the theme you just installed.
I don’t think I have FTP access-how do you acess that to check?
someone else started this site for me and just gave me my password and site.
Thanks
since you don’t know ftp – use your host’s file manager and navigate to the /wp-content/themes folder
inside that folder find and rename /steampunk/
this will bring up default theme so you can find another theme to use
You need an FTP client (such as FileZilla). Are you in touch with the person who set up the site for you? Ask him/her to either give you FTP access (they need to give you the FTP user name, FTP password and domain name) or go in there themselves and fix it.
EDIT: Yes, do what Samuel B says, that’s a good suggestion!
Ok thanks for your help! I will contact him
