I copied all website files/database from a testing server to the live server. I realized all the product pages were broken (blank white pages).

Upon checking error_log, I found the following error:

————————————————————————————————————–
[17-Nov-2018 22:45:44 UTC] PHP Fatal error: Can’t use method return value in write context in /home2/precipe9/storage/modification/catalog/controller/product/product.php on line 312
————————————————————————————————————–

This is what line 312 reads:

————————————————————————————————————–
$product_option_image_width = !empty($this->config->get(‘theme_’ . $this->config->get(‘config_theme’) . ‘_image_option_width’)) ? $this->config->get(‘theme_’ . $this->config->get(‘config_theme’) . ‘_image_option_width’) : 50;
$product_option_image_height = !empty($this->config->get(‘theme_’ . $this->config->get(‘config_theme’) . ‘_image_option_height’)) ? $this->config->get(‘theme_’ . $this->config->get(‘config_theme’) . ‘_image_option_height’) : 50;
————————————————————————————————————–

I temporarily changed it to read:

————————————————————————————————————–
$product_option_image_width = “50″;
$product_option_image_height = “50″;
————————————————————————————————————–

Any now the product pages work but hoping for a better solution.

When I copied the files from the testing server to the live server, I manually copied “/public_html/storage” by hand to the live server. Was this correct?

Any help?
