The error refers to code in your child theme (functions.php line 301).
You presumably have some custom code on your site that references the Toolset APIs or similar, can you share the code where the error occurs and we can look to see if we can spot the issue. If you are not comfortable opening and editing that file, you can copy the whole file to somewhere like dropbox and share a link here.
I should point out that support doesn't cover custom code, but we'll be happy to at least take a look to see if we can spot the problem.
I correct it to the capital letters "OBJECT" in the lone 301.
I think it is fixed now.
But I have other errors now:
- Notice: Undefined variable: html_output in /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-content/themes/totalbusiness-child/functions.php on line 262
See attached the code for line 262.
- Notice: Undefined variable: html_output in /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-content/themes/totalbusiness-child/functions.php on line 328
See attached the code for line 328.
sorry, here is another error:
Fatal error: Uncaught ArgumentCountError: Too few arguments to function auto_process_sort_field(), 1 passed in /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/class-wp-hook.php on line 289 and exactly 2 expected in /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-content/themes/totalbusiness-child/functions.php:358 Stack trace: #0 /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/class-wp-hook.php(289): auto_process_sort_field(13603) #1 /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #2 /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/plugin.php(484): WP_Hook->do_action(Array) #3 /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/post.php(4309): do_action('save_post', 13603, Object(WP_Post), false) #4 /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-includes/revision.php(334): wp_insert_po in /var/www/vhosts/hydrotrenchdrains.com/demo.hydrotrenchdrains.com/wp-content/themes/totalbusiness-child/functions.php on line 358
For the first error, I guess that you can patch the file by adding the following line at respectively lines 227, 302.
$html_output = "";
Regarding the last error, I think that you will have to check with your theme authors. They are adding a function as a hook with an error. The function expects two arguments, but it only gets 1.
