News Manager 3.0 is almost totally backwards compatible with 2.2.4 and later. To upgrade 2.x to 3.0 you just have to uncompress the zipfile and upload/copy its contents (news_manager.php and news_manager folder) to your site's plugins folder, overwriting all existing files. But there are a some changes in this version's default behaviour.
For full backwards compatibility, insert this in your site's gsconfig.php file:
And if you don't want that your posts are inserted in your site's sitemap.xml:
If you prefer, you could also simply upgrade and then change the settings you need:
Since 3.0 automatically generated excerpts don't truncate words.
If you prefer it the old way, enable Custom Settings and enter:
Also, a "read more" link is appended to end of excerpts (if needed). To disable this, select:
News Manager Settings -> Add "read more" link to excerpts -> No
Since 3.0 the default page navigation is numbered and with previous and next page links, as opposed to the Older/Newer posts used in 2.x, that can be enabked with Custom settting:
Pagination index (page= or page/ in URL) starts now at 1 instead of 0 by default.
This can be changed back to the old way with a this gsconfig.php setting:
Post title and <title> tag
News Manager 3.0 tries to insert post titles in the
<title> tag when in the single-post view, for better SEO.
You shouldn't have issues if you're already using the News Manager Title plugin or if you're using function
nm_post_title like this:
<title><?php nm_post_title(...) or ... ?></title>
However you can have trouble with this (duplicate title in the page or in the
<title> tag) if:
<title><?php nm_post_title(...); ... ?></title>(with a semicolon instead of "or")
To easily fix any of those, enable Custom Settings and enter:
Another option for case 1 is inserting the get_header tag in your template (before the closing
</head>). There are many other plugins that require it anyway.
For case 2, you can make some change to the code in the
<title> tag. If you don't know how, ask in the forum support thread.
