Title: plugin PHP compatible with 7-73? Last modified: November 22, 2019 --- # plugin PHP compatible with 7-73? * Resolved [ChangeAgent](https://wordpress.org/support/users/changeagent/) * (@changeagent) * [6 years, 5 months ago](https://wordpress.org/support/topic/plugin-php-compatible-with-7-73/) * I am running PHP 7-71 (7.1.32) presently. If I update to any higher version my site throws errors. Could this be this plugin? I am asking as the PHP Compatibility Checker seems to be unable to scan it and/or seems to think it is not working properly.
