Dear Sir/Madam,

after updating to latest version 8.0.7 single post pages have stop working and i get the following php error.

AH01071: Got error 'PHP message: PHP Warning: Undefined variable $meta_size in /var/www/vhosts/......................./wp-content/themes/soledad/functions.php on line 4606PHP message: PHP Fatal error: Uncaught TypeError: implode(): Argument #1 ($pieces) must be of type array, string given in /var/www/vhosts/................../wp-content/themes/soledad/functions.php:4606 Stack trace: #0 /var/www/vhosts/....................../wp-content/themes/soledad/functions.php(4606): implode() #1 /var/www/vhosts/............................/wp-content/themes/soledad/content-single.php(226): penci_image_datasize() #2 /var/www/vhosts/....................../wp-includes/template.php(772): require('...') #3 /var/www/vhosts/......................../wp-includes/template.php(716): load_template() #4 /var/www/vhosts/................................../wp-includes/general-template.php(204): locate_template() #5 /var/www/vhosts/.........................../wp-content/themes/soledad/single.php(159): get_template_part() #6 /var/www/vhosts/......................./wp-includes/template-loader.php(106): include('...') #7 /var/www/v...'

When swtiching from child theme to normal theme everything is ok.

Child theme does not have any functions or hard customizations just using it to ovverride css styles and add google analytics code.

Any ideas?
