@photocrati – Hi, I’m new to WordPress and I have encountered a problem with NextGEN Gallery and PHP 7.1.1. Some messages come up on the site background, always the same, repeated like this:
Warning: Parameter 2 to M_DataMapper::set_custom_wp_query_where() expected to be a reference, value given in C:\xampp\htdocs\site1\wp-includes\class-wp-hook.php on line 298
When I deactivate NextGEN Gallery, the site is normal.
On another server with PHP 5.x, NextGEN Gallery works without Warnings.
My developement configuration is:
Windows 7 Home Premium SP1
WordPress 4.7.2
– Theme Twenty Fifteeen
– NextGEN Gallery 2.1.79
running on XAMPP for Windows 7.1.1 (Control Center 3.2.2)
– with Apache 2.4.25
– MySQL (MariaDB 10.1.21)
– PHP 7.1.1
Can you help?
PS: When you google the message text, you can find several websites running with exact the same warnings on the background area.
Thanks. Coolman111
