News Manager (updated)

[judgedredd]

I have just downloaded the News Manager (Updated) plugin and uploaded it to the plugins folder as per the instructions.

I found that the plugin did NOT appear in the plugins tab. I logged out, logged back in, refreshed the page, emptied the browser cache, re-logged back in and ..... nothing. News Manager (Updated) not showing in the plugins tab. I then tried installing the folders/files in the root of the plugins folder instead of uploading the plugin into its own folder. Still nothing.

I have attached a screenshot of the plugins folder on my server.

In the image above, the folders on the right are are as follows:
anonymous_data - plugin folder
browser - from News Manager plugin folder
inc - from News Manager plugin folder
InnovationPlugin - plugin folder
lang - from News Manager plugin folder
NewsManager - News Manager (Updated) plugin folder
template - from News Manager plugin folder

What do I need to do to get everything to work?

I have added the .htaccess code for this plugin into the .htaccess file in the root of the CMS folder instead of the plugins folder, seeing as the code was nearly identical to the original .htaccess file.

The version of PHP on my server is 7.2
Version of Get Simple is 3.3.16
Server has the LAMP stack
Site address is http://theforensicnurse.org (GetSimple folder is under /cms)
News Manager (updated) Plugin is the latest version
Two default plugins already installed (came with the GS download) and showing in the plugins tab
Deactivated and re-activated the two default plugins withpout any problems
