Well since this doesn’t apply to all posts, and you only want to do this with old posts, it makes it pretty complicated and you most likely aren’t going to find a plugin to handle this. Let me ask you this, what “like” buttons are you trying to preserve and what are you using to display those like buttons.

What does is the context of “columnas” here, is that a category or sub-section, or will that be in every single url?

Well you can’t use that code in a stylesheet, you need to use the relative path to the stylesheet. Where is your images directory located?

I’m not sure where your confusion lies. You need to add the loop code to your template file to loop through the posts, otherwise you can only access one post with the template tags.

Do you have a link where posts are supposed to display?

Look into wp_oembed_get() If you pass in the url it will do a lot of the work for you.

That’s a tough question to answer, but I can tell you it has little to do with performance. It is more of a common practice thing related to user experience. Categories are typically used as a high level division of subject matter, and a post usually only fits under one or maybe two categories. And when it becomes common practice, people come to expect similar functionality and usage when on new sites.

They are saying the same thing I was saying, that the wp-content directory and theme files will be unaffected by the upgrade. What you need to be sure of is that no core files have been changed.
