Not afraid to edit files. Wasn’t sure if the devs were aware of this one so I thought I’d post it. * (FWIW – I have so many other plugins with issues, I fear I’m a ways off from PHP7) * [ArnaudBan](https://wordpress.org/support/users/arnaudban/) * (@arnaudban) * [9 years, 5 months ago](https://wordpress.org/support/topic/php7-error-9/#post-8617420) * Thank you Peter, editing the file work fine ! * [luntrasul](https://wordpress.org/support/users/luntrasul/) * (@luntrasul) * [9 years, 2 months ago](https://wordpress.org/support/topic/php7-error-9/#post-8961327) * Yes work, thx [@petervanderdoes](https://wordpress.org/support/users/petervanderdoes/) * [JohnRDOrazio](https://wordpress.org/support/users/lwangaman/) * (@lwangaman) * [9 years, 2 months ago](https://wordpress.org/support/topic/php7-error-9/#post-8974387) * I was having the same problem after updating to PHP 7.1, I was getting the same error in my logs and I figured out to change the string definition to an array for the $groupby_sql variable.
