QUESTION Newbie asking for tags and categories, posts

[pablito]

Maybe it was not the best idea but i tried it on a production new site.
Now, the site is broken. How can I revert back to the former situation ?
Edit : I removed the folders of the plug in and the php file and it was back ok.

Did you really risk your production site ? You didn't make a backup first ?
That is not the way how to work with production sites.
Install a fresh new GS setup and then try the News/Blog plugin.

I was able to get back but why is it always so risky to try new plug ins ? 
Nevertheless, I managed to get back to normal and have been trying yesterday night to play on a local installation to see if I can do what I want. 

Globally, the plug-in is good and fulfill my needs. 
I might need to change a little the code inside to get what I want. 

One thing, it is absolutely necessary to change the canonical as precised here : 

SEO
- See function/template tag nm_post_title (since News Manager 2.3.x) to have a proper <title>
- Recommended:
(update) Since News Manager 3.5:
Edit your template(s) and change 

Code:

get_header

 to 

Code:

nm_get_header

 (or 

Code:

get_i18n_header

 to 

Code:

nm_get_i18n_header

 if you use mvlcek's *I18N* plugin). This way your posts, archives and tag pages will have proper canonical meta tags.
Before News Manager 3.5:
Change your template's 

Code:

<?php get_header(); ?>

 to:

Code:

<?php get_header(false); ?>

 - This way your site won't have the canonical meta tag (or else, because of the way GetSimple works, all posts have the same canonical URL, that of the news page)

I am working in SEO and I was terrified this feature is not built in.

You really have to master your seo to use this tool. 
That makes me feel sad actually.
