I deleted an Mailchimp admin account which was linked with the Mailchimp API I was using to sign up subscribers on my wordpress site(using Mailchimp widget) and as a result I cannot login to the mailchimp plugin(Version 1.5.7) and I get the error "Fatal error: Cannot use object of type WP_Error as array in /home/priorafr/public_html/[login to view URL] on line 584"
I have researched the solution and its simply deleting the old Mailchimp API associated with the site found at" [login to view URL]"
As a newbie am stuck as I seem not to be locating the file or folder on my file manager where the old Mailchimp API is stored so that I can remove it and hence login on the plugin and update the new Mailchimp API.
I need someone with mailchimp, wordpress and php to assist me locate this "[login to view URL]" to remove the old API.
Its a micro task which can't take 10 minutes for an expert guru! (Nb: I will also need to be taught what was done so that I can fix such an issue next time)
