Fatal error: Call to undefined function c2c_get_custom() in /home//custom.php

Hi James,
Thanks for helping, but it’s not solved the problem. I click on the post view it’s display

https://www.viet.seaccusa.org/2012/11/19/empowering-community-promoting-business/

If I click on the sidebar link, it shows the fatal error that means something is wrong with the sidebar or the pages. Index page has fatal error too.

Thanks

Hi James,
I tried deactivated all plugins, but it didn’t solve the problem, but new theme is working well. What I have to do with the old theme to make it works. Thanks

Hi,

I am not sure where it come from but under my organization theme name on Dashboard.
I think if I can change this code to basic nav bar, it may work

`$nav1 = update($nav1, c2c_get_custom(‘nav1’), $overwrite);

Thanks

Thanks for help. I don’t know who designed the theme to contact. People use to see our old website that why I try to fix it.

I deleted line by line, but it shows the same error that mean the codes were not function well with wp new update
