I have a problem in the presentation of additional images with outstanding image
In short, the problem that in the event of a picture of it works without any problem
But in the absence of a photo showing I have a problem, namely, (additional image)

rning: error_log() has been disabled for security reasons in /public_html/wp-includes/wp-db.php on line 1036
