Issue with latest BeTheme Update

dreamcars_ch

After some time i've update from an older version of BeTheme to the latest version (also went from Wordpress 4.x to latest 5.x) and now i get the following error when i try to access some gallery pages:

Fatal error: Uncaught Error: Call to undefined function mfn_builder_print() in /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/wp-content/themes/betheme-child-mydomain/functions/custom_muffin_extenstion.php:15 Stack trace: #0 /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/wp-content/themes/betheme-child-mydomain/single-car.php(38): dmc_mfn_builder_print(2419, Array, true) #1 /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/wp-includes/template-loader.php(98): include('/home/httpd/vho...') #2 /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/wp-blog-header.php(19): require_once('/home/httpd/vho...') #3 /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/index.php(17): require('/home/httpd/vho...') #4 {main} thrown in /home/httpd/vhosts/placeholder.abc/dev.placeholder.abc/cms/wp-content/themes/betheme-child-mydomain/functions/custom_muffin_extenstion.php on line 15

I've found a similar thread but it was with slightly different parameters so i do not know how to get this fixed.

Thanks

Hey,

from what version were you updating?

Please try to disable all of your plugins and check if your PHP version is set to 7.0 at least.

thanks

Hi Bryan,
PHP Version is set to 7.2, the old BeTheme was ~ 1.5y old Version and it's a sub-theme used.
I found some information that sub-theme handling / calling got changed but only other examples and i was not successful to adapt for my sub-theme.

this is the code from the file where the error happens (had to remove the first line with php as it blocked me from posting):

if( ! function_exists( 'dmc_mfn_builder_print' ) )
{
/**
* @DMC Extension of PRINT Muffin Builder
*
* @param int $post_id
* @param bool $content_field
*/
function dmc_mfn_builder_print( $post_id, $custom_fields = array(), $content_field = false ){

ob_start();

mfn_builder_print($post_id, $content_field);

$out = ob_get_contents();

ob_end_clean();

return dmc_parse_placeholders($out, $custom_fields);
}

}

Thanks,
Thomas

Please update your theme to the latest version, here is an instruction on how to update the theme:
http://themes.muffingroup.com/betheme/documentation/#general
Theme updates will not delete your content unless you have changed the
files directly in which case we suggest using a child theme.
We also recommend creating a backup file.
Please remove the theme completely from your theme folder and install a
fresh copy. Do not overwrite files.

thanks

Hi Pablo,
I've just updated from 21.5.3 to 21.5.4 (and before the update was from some Version 20.x.x where it was working) but still the same issue.
There is already a child-theme (called it sub-theme before, sorry) in place and the file where the error occurs (the code i posted before) is also in this child-theme.
I've found here some similar issue but the code in my file is more complex and wasn't able to adapt it similar to that posted solution:

Thanks,

Sorry, but we do not help with the theme files customizations.

If your problem is related to them, our hands are tied.

But yes, we had to change it - and you should find these kind of codes "mfn_opts_show()" with finder in your IDE easily.

Hi Pablo,
That's the only file with code in this child-theme i could find and i thought it was somehow generated by the theme itself - but looks like the original web-designer made here some own customization.
So there is also no paid support available for such cases to get help?
Thanks,
Thomas

You didn't attach the wordpress login credentials - we need them too.

Please send what I asked you before once more.

Hey,

Sorry i didn't see the post here, i've just sent the data via email.

Thanks,

So, I commented out the old BeTheme version of displaying the post and appended the new one.

http://prntscr.com/r7cv2u

And it works - the problem was with our old function used in some file.

Hey Pablo,

You are awesome - i thought that it's just some function like this but couldn't get to find out how to change on my own.

Wish you a wonderful evening.

Thanks,

You guys ever hear of backwards compatibility? Might be worth checking out.

Phil

karlkroeber,

Can you explain me in more detail what do you mean by "backwards compatibility", please?

Thanks
