I was trying to edit the footer on Activello’s extras file when I received an error. I tried to undo the change exactly to how it was originally but nothing changed. I cannot access any other parts of my dashboard. I cannot delete or change anything since all I get is an error page. Please can someone help me!!
Sorry to hear of the problem you are having.
To recover from this error please delete the theme directory from your WordPress install and upload there new theme directory by downloading it from the page Activello - Simple Multipurpose Blog Theme - Colorlib
You can do this using FTP or file manager as described on the following page.
