php error instead of custom 404 page

DebsWebs

Hi,

I set up a custom 404 page using the built-in 404 page in the theme settings. It was working perfectly for a while, but now, it has started displaying a php error instead of the error page itself.

Here is what I get now instead of the error page.

"

Fatal error: Uncaught Error: Call to undefined function
mfn_builder_print() in
/hermes/walnaweb06a/b2072/moo.jmhoffman/advancedir/wp-content/themes/betheme-child/404.php:61

Can you please help me get my 404 error page working again?

Here is the link to the site:

https://www.advanced-ir.com/

and here is the link that caused the error code to appear (although it appears for any incorrect page url)

Thanks.

Hi,

Is your php version 7 or higher?

Did you test it with all of the plugins disabled? (and cleared the cache after disabling the plugins?)

Is your BeTheme and WordPress up to date?

Thanks

Hi Pablo,

My server is using php version 7.1.

WordPress and the BeTheme are both up-to-date.

I have disabled all plugins and cleared the cache and the problem persists.

Any other thoughts?

It was working when I first set the 404 page up, but then at some point in the few weeks since the site was completed, it stopped working.

Hello,

those might be recent code changes for the theme, that impact the child theme.

Please switch to the parent theme and see if this issue persists.

thanks

Yes!!! That was the problem. Now, how do I fix it?

Hi,

Some time ago, we released the update for the Child Theme

Now, if you will make some changes in your child theme, you don't have to
provide the informations in functions.php which files you changed - now,
it's automatically apply these changes.
To make your Child Theme work again, you have to find and replace the 'mfn_opts_show()' to 'echo mfn_opts_get()' in files which were modified.
After that, everything should be working fine, we had to make that change because of the new envato rules, more about it here: https://help.author.envato.com/hc/en-us/articles/360000481243#h_674316188621522302914837

Thanks

Thanks for the update. Is the code above supposed to be in the functions.php file? I am not finding anything that looks like that in my functions.php file for my child theme or in the main Betheme functions file. Please let me know where I need to look for that code, or let me know where I can find the child theme update that you refer to.

I haven't modified any files except for the functions.php and the 404.php. I don't see the lines of code you are referring to in the functions.php file.

In the 404.php this is the code that I have. I don't see any instances of the 'mfn_opts_show()'. I'm not a coder so I may be misunderstanding what I'm supposed to do.

I did create a custom page to use for the 404 page and selected to use it as the 404 page.

Sorry, your problem is not related with the "mfn_opts_show()" - I didn't read the whole error at the beginning.

To solve your problem, you have to change the old function 'mfn_builder_print' to 'Mfn_Builder_Front'.

See screen:

http://prntscr.com/n9zdci

Change the red rectangle to green rectangle, code below:

$mfn_builder = new Mfn_Builder_Front($customID, true);
                   $mfn_builder->show();

Thanks
