I know i have to look on http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory#Using_a_pre-existing_subdirectory_install I swear that i check this info before writing here (and i re-read what i write before posting), but i don't get it... well, now i'm getting a litle bit more :)
Sorry, but there are somethings i don't get:
1) So first, i have to install, activate and configure the plugins i have on root on (wp), before doing anything else?
2) You said:
So http://cortometrajesonline.com/wp/ or whatever would be a clean site. Then I'd export all my content from http://cortometrajesonline.com and import it to my new site, add users and, if that works, use the giving WP it's own directory trick.
Before doing that thing of moving files between directories, i have to export my content from root to wp, no? Plugins info that not work with custom fields will not be exported, no? I will loose it...
3) After installing, activating and configuring the plugins i have to Copy (NOT MOVE!) the index.php and .htaccess files from the (wp) directory into the root directory of my site, it means i will OVERWRITE root index.php and .htacccess, no? So will happen with wp-config.php
4) In the future when i have to update wordpress, will i loose the changes i'm going to make? I mean, Will the update owerwrite the index.php file that (will) says
5) ok, i'm getting it... so, before tricking i will see if my site works on http://www.cortometrajesonline.com/wp, and then if it works i will make the trick and the frontend will be at the root and the admin panel at (wp)... i see light at the end of the tunnel! :)
I know, I'm a pain in the ass :) it's just i don't want mess things...
