Did you make the changes in the 1)core file or 2)a child theme?
1) Don’t do it again! You’ll need to restore the core file and start again with a Child Theme
2) You should have taken a copy of the core file and copied it to /wp-content/themes/customizr-child/parts and edited it there. Check line #154 and see what you’ve done or come back with more information.
Did you see this Snippet?
Do not edit the theme itself. First create a child theme for your changes. For now, upload a fresh, unpacked copy of the theme to wp-content/themes using FTP.
Thank you I got it fixed through my hosting and a new install.. The other problem was it would not let me even see line 154 without just showing the error… I will use child themes from now on! Thank you for the tips!
