Problem submitting an idea
-
Hello, I have problems with this plugin. When I want to push an idea it doesn’t want to submit. It keeps saying ‘Hold on’ with a turning spinner. When I look in the logs I see:
[Mon Dec 03 14:30:04 2018] [error] PHP Fatal error: Uncaught Error: Call to undefined function sanitize_textarea_field() in ***/wp-content/plugins/ideapush/inc/functions/create-idea.php:18\nStack trace:\n#0 ***/wp-includes/plugin.php(525): idea_push_create_idea(”)\n#1 ***/wp-admin/admin-ajax.php(89): do_action(‘wp_ajax_create_…’)\n#2 {main}\n thrown in ***/wp-content/plugins/ideapush/inc/functions/create-idea.php on line 18, referer: https://***/ideeen-box/
Then I found this page: https://developer.ww.wp.xz.cn/reference/functions/sanitize_textarea_field/. In my ‘formatting.php’ file I couldn’t find the function ‘sanitize_textarea_field()’. It seems like this function was introduced in WordPress version 4.7.0. However the plugin page says that the plugin is compatible for version 4.0 or higher.
What could solve the problem?
WordPress version: 4.5.2
PHP version: 7.0.18
