Wordpress keeps redirecting to install-php after migration

Question

Here s my situation  I have followed the exact instructions on wordpress codex page about moving a site to another server  Here are the step s i have taken    Export a copy of my database Make a new database in the new server Import the database I exported earlier Upload a copy of my Wordpress files via Ftp Use this script to change all my local url s to new one s  Make changes to my wp-config php file according to the new server I did not forget table prefix  Although it has some uppercase characters in it     And then when I try to open my site on the new location it just directs me to wp-admin install php Now just to make the scenario clearer  The destination folder on live server  is a sub directori in a public html folder which already has another wordpress install inside it I m saying this just in case it should matter   My  htaccess looks like this        BEGIN WordPress  lt IfModule mod rewrite c gt  RewriteEngine On RewriteBase  subDirectoryName  RewriteRule  index  php  -  L  RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -d RewriteRule    subDirectoryName index php  L   lt  IfModule gt     END WordPress   I have tried checking and repairing my tables via phpMyadmin but everything seems to be ok there and has no effect on the problem   I also tried emptying the database on the live server and go through with the install  And it installs with no problems and everything works fine but  well I have no use for another clean install  But I think this at least rules out any trouble with wp-config file  I m using Wordpress Version 3 3 1  So I guess the big question I m left with is  Why isn t wordpress recognizing my Install after migration    Any help much appreciated

It seems that in general  this happens when Wordpress doesn t find the site information in the expected places  tables  in the database  It thinks no site has been created yet  so it starts going through the installation process  This situation means that   Wordpress WAS ABLE to connect to a database  If it didn t  it would say there was an error and refuse to install or do anything else  AND  it didn t find the things it was looking for in the expected places in the database it connected to   Just to be clear  both 1  and 2  are happening when you see this symptom  Possible causes   Wrong database  You re working on several projects and you copied and pasted wrong database name  database host  or table prefix to the wp-config file  So now  you re unwittingly destroying ANOTHER client s website while agonizing over why isn t THIS website working at all   Wrong database prefix  You can put several Wordpress sites in one database by using different prefixes for each  Make sure the tables in the database have the same prefixes as you entered in your wp-config  So  if wp-config says   table prefix    wp    Check that the tables in your database are called  quot wp options quot   etc  and not  quot WP options quot    quot mysite options quot  or something like that   The data in the database is corrupted  Maybe you messed up while importing the sql dump  you imported a truncated file  a file belonging to some other project  or whatever

Well finally I have solved the problem  And surprise  surprise It was the freaking UPPERCASE letter in my table prefix  I had it this way in my wp-config file wp C5n but for some reason most of the tables got a prefix wp c5n  But not all  So what id did was I changed my table prefix in wp config file to all lowercase and then went through all the tables by hand via phpMyadmin to see If there s any uppercase tables left  There where about 3  They were inside usermeta table and inside options table  Now finally everything is working  Did a quick search through wordpress codex but did not find anything mentioning not to use uppercase characters

This happened to me after I copy migrated an existing website to WP Engine and forgot to do one thing required by WP Engine   Update the WordPress core installation of the site that is being copied to the latest version    So here was the problem then   My old site that I was copying from another server to WP Engine had version 4 0  However  when you copy an existing site to WP Engine  you don t copy the WordPress core files  you only copy the contents of wp-content and the state  or snapshot  of the existing database  So the state of the database for my existing site was for an installation running WP 4 0  Nevertheless  when you create a new WordPress install on WP Engine  that install is created with the latest version of WordPress  which  at the time happened to be version 4 0 1  so that means the core files on the destination  WP Engine  were for a 4 0 1 installation but the database snapshot I was gonna import into WP Engine was for version 4 0  So when I overwrote the default WP Engine database with the import of the copy the database of my old site  I got the redirection error to the install script    So to fix it  I just logged into the WordPress admin site of the site on WP Engine  made sure to reset the file permissions  by clicking the blue button   which  you sometimes have to do on WP Engine  and then re-installed the WordPress core  which  basically updates your database so that internally the db state was for a WordPress 4 0 1 install and the core files also match the version    Took me a while to figure out what was going on

I would check two things    First  I would check the url that is configured in the database  Check the wp options table and the values of the  siteurl  and  home  options  it is possible that you need to update them if your domain has changed  Another option is that your Apache server could not get the  htaccess  Check if the  AllowOverride  option is  all  in the httpd conf file    I hope it helps
