In one of my websites under Dashboard-> All in one Seo -> General Settings-> Home page settings->Home description I had description up-to 167 characters.
But in live website, it doesn't shows full description as you can see it using source code of my home page.
I had same description in Home page->edit->description area.
How to resolve this issue, any suggestions
If you are a developer, you can increase the meta description character limit of this plugin. Consider this response from a forum: http://semperfiwebdesign.com/forum/optimizing/description-tag-length/#p2554
To increase the description characters, just open up aioseop.class.php and change line 8:
var $maximum_description_length = 160;
to
var $maximum_description_length = 300;
