Hi There,
Please can you tell me how I can fix this? Please see below, Wordfence is seeing this as a security issue.
Many thanks. Kind Regards, Lauren.

Type: Plugin Abandoned

Plugin Name: Itthinx Updates
Current Plugin Version: 1.2.0
Last Updated: 21/06/2017
Details: It was last updated 3 years 4 months ago and tested up to WordPress 10.0.0. Plugins can be removed from wordpress.org for various reasons. This can include benign issues like a plugin author discontinuing development or moving the plugin distribution to their own site, but some might also be due to security issues. In any case, future updates may or may not be available, so it is worth investigating the cause and deciding whether to temporarily or permanently replace or remove the plugin. Get more information.
