i put wordpress in sub-directory of a drupal site now when i tried to install this error “ERROR: you must provide an e-mail address” appear.
Either there is issues with wp-config.php file (25% chance) or the configuration of php.ini file is incorrectly set (>70% chance). Hosting environment, other than php.inifile settings can contribute to rest (<5% chance).
As basically Drupal is also running, you need to increase the alloted maximum memory and POST size. POST is the HTML POST what carries the info (email in your case) from your form filed to database. That basically is failing.
Login though shell as root user (taking Terminal and standard unix commands for a Debian Server and nano as text editor) and open the php.ini file :
Running this command will show you the path of php.inifile :
sudo locate php.ini
Usually it will be :
/etc/php5/apache2/php.ini
Open with text editor :
nano /etc/php5/apache2/php.ini
Use ‘where’ function its ^ + W in OS X) and find the lines :
php_value upload_max_filesize
and
php_value post_max_size
You can temporarily disable (comment out by ; followed by a space before the lines) and restart Apache2, however it is not recommended for security reasons.
And increase the values like somewhat :
php_value upload_max_filesize 256M
php_value post_max_size 512M
Write out :
^ + O
Also increase the php memory value in WordPress’s .htaccess :
php_value memory_limit 256M
If it throws 500 internal server error, wrap it :
<IfModule mod_php5.c>
php_value memory_limit 256M
</IfModule>
Change default php memory limit to less than allocated by server, i.e. a bit less than 256MB.
Restart Apache :
/etc/init.d/apache2 restart
You need to enable:
extension=suhosin.so
