mysql - Will rewriting the Joomla system files, remove my articles and data? -

-

as cannot access admin area, told joomla system files might have problems , best download latest version , rewrite on host. website running , up. if replace joomla package on host, remove or change on website? have on website, such plugins, template, articles, music, mysql, , on. change? based on joomla 1.5.

if yes, suggestion?

it's not idea on live server because may broke site. instead of prepare local server , download site it. download dump of server database , restore locally.

on local copy need change configuration.php file local database settings (username, password , database) , paths tmp , cache directories.

when local site , running can try replace old files new ones, don't overwrite configuration.php file. before replacing files not bad idea keep copy of site files. way, don't try overwrite files higher versions 1.5 : won't work. last stable package (discontinued) 1.5 1.5.26, available through joomlacode : http://joomlacode.org/gf/project/joomla/frs/

if solves issue can upload files downloaded joomla server (except configuration.php) .

regards!

edit: can see, articles not removed, stored on database.
