i am installing wordpress on 5 domains using one database but it only installs on 1st domain but when i try to install it on 2nd domain then i get this msg >>> How can i resolve this problem what file i have to edit for this, please tell me ASAP...Thanks!
yes, but this is different method i just want this if i update one blog then remaining 4 blogs will automatically update...
Oh, I got it what you mean. You are trying to install it over the same wordpress installation and same database. Then you need wordpress mu (multi user). A small manual modification to wp-config.php file can also make it work (setting table_prefix with respect HTTP_HOST being accessed) but its not recommeded because updating wordpress will not update all database tables of all sites at once. Wordpress MU is recommended.
dude i just want keep only one database and want to install all blogs using the same database so in case if i edit one blog then all blog should be edited with it...so any idea about this?
Do you mean, all blogs contain the same content (articles, posts, comments, feeds, etc) like mirrors on different domains? Changes in the blog should affect all domains?
This cannot be done by default wordpress installation. But a custom wordpress plugin that updates the site links on the fly can help achieve this. EDIT: There it is: http://mcaleavy.org/code/domain-mirror/ See if it works for you. It has more options than changing just the links.
Thanks for everything but is it 100% sure that it couldn't be possible without plugin? i mean is this possible to may change occurs to just edit any wordpress file?
