Bug report: PHP 7.2 fatal error

Resolved

(@abigailm)

With an upgrade on a production site to PHP 7.2, some pages would not load and error logs shows this error:

PHP Fatal error:  Uncaught Error: Call to undefined function mb_strpos() in /.../wp-content/plugins/page-list/page-list.php:448
Stack trace:
#0 /..../wp-content/plugins/page-list/page-list.php(346): pagelist_unqprfx_parse_content('xxxxxxxx...', 250, 1, 1, '<!--more-->')

#2 [internal function]: do_shortcode_tag(Array)
#3 /..../wp-includes/shortcodes.php(197): preg_replace_callback('/\\[(\\[?)(pageli...', 'do_shortcode_ta...', 'xxxxxxxxxx...')
#4 /..../wp-includes/class-wp-hook.php(286): do_shortcode('xxxxxxx')
#5 /.../wp-includes/plugin.php(203): WP_Hook->apply_filters('xxxxxx...', Array)
#6 /..../wp-include in /..../wp-content/plugins/page-list/page-list.php on line 448

I have reverted to PHP 7.1 so I don’t need further assistance, but am reporting this for purposes of development.

Hey @abigailm

Seems like your server config is missing MBString extension.

mb_strpos() is still supported and not deprecated function in PHP 7.2 – http://php.net/manual/en/function.mb-strpos.php
