Hi
well, I’ll explain again the problem, to help you understand it better.

We have installed and activated the “Polylang for woocommerce” plugin: then, the following error appeared in the display of each product sheet (both back-end and front-end).

Fatal error: Uncaught Error: Object of class WP_Error could not be converted to string in /home/customer/www/cbn.digitalsfera.it/public_html/wp-content/themes/enfold/config-woocommerce/config.php:807 Stack trace: #0 /home/customer/www/cbn.digitalsfera.it/public_html/wp-includes/class-wp-hook.php(307): avia_woocommerce_breadcrumb(Array, Array) #1 /home/customer/www/cbn.digitalsfera.it/public_html/wp-includes/plugin.php(189): WP_Hook->apply_filters(Array, Array) #2 /home/customer/www/cbn.digitalsfera.it/public_html/wp-content/themes/enfold/framework/php/class-breadcrumb-trail.php(419): apply_filters(‘avia_breadcrumb…’, Array, Array) #3 /home/customer/www/cbn.digitalsfera.it/public_html/wp-content/themes/enfold/functions-enfold.php(664): avia_breadcrumb_trail->get_trail(Array) #4 /home/customer/www/cbn.digitalsfera.it/public_html/wp-content/themes/enfold/config-woocommerce/config.php(920): avia_title(Array) #5 /home/customer/www/cbn.digitalsfera.it/public_html/wp-includes/class-wp-hook.php(307): avia_woocommerce_before_mai in /home/customer/www/cbn.digitalsfera.it/public_html/wp-content/themes/enfold/config-woocommerce/config.php on line 807

We found that the problem only occurs when activating Enfold breadcrumbs.
Then, from Enfold “Page / Post> Layout> Title Bar Settings”:

– By setting “Display Title and breadcrumb” -> the above error is displayed
– By setting “Show title only” -> the error is not displayed

At the moment the error is not displayed cause the site is online and we have set “Show title only” as breadcrumb. However, we need you to fix the bug above cause we would like to go back to the “Display title and breadcrumb” option for SEO reasons.

So, obviously at the moment the site is not in error, because we have deactivated the breadcrumbs (the site is not in staging but it is online). No longer having a test environment, are you able to verify this problem independently on your own environment?

Hope that you understand better the situation
