Si obtiene un error como este, hay un plugin u otra función llamada en su tema que no tiene. ¿Cómo solucionarlo? Hay varias maneras: eliminar el código, comprobar el error, obtener el plugin necesario o actualizar WordPress si es necesario. En este rápido post de consejos de WordPress, veremos cómo corregir estos errores con una etiqueta condicional y una función PHP conocida como: function_exists.
Si obtiene un error como Fatal error: Call to undefined function the_title_attribute() puedes simplemente reemplazar cualquier instancia de the_title_attribute con lo siguiente:
<?php if (function_exists('the_title_attribute')) { the_title_attribute(); } ?>
En este caso, también puedes ir un paso más allá añadiendo una sentencia else.
<?php if (function_exists('el_atributo_título')) { the_title_attribute(); } else { the_title(); } ?>
Antes de probar un tema nuevo en un sitio de producción, asegúrese de previsualizarlo primero y, a continuación, resuelva todos los errores (si los hay).

Hi ive just used:
And it worked for that file where i was previously getting the Fatal error.
Im now trying it for 2 sidebars of my theme so that i can place them into their own .php files.
The sidebars are named leftsidebar and rightsidebar, so i use the code as above and put in get_leftsidebar and get_rightsidebar but it goes wrong somehow and the layout gets messed up, im not sure where i may be making the mistake here though, any ideas please?
Thanks
John
