 * Hi, I have Joomla 1.5 on the main domain and WordPress in a subdomain and am 
   now trying to Import Joomla content to the sub-domain as WP. Both databases are
   on the same server and I have created a new SQL user with full privileges on 
   both databases. I have verified all settings to be correct and have checked FAQs
   and increased memory limits as recommended but get a blank screen even at the
   Test Database option. I get no error messages nor does there seem to be a timeout(
   I get impatient after a minute or two).

 * Could you try to install WordPress on your local computer, copy the Joomla database
   on your local MySQL and run the import in local?
    You’ll be able to see if it
   comes from your server or not.

 * I don’t have MySQL on my PC or, to be honest, understanding of how to run it 
   if I did.

 * Here is a tutorial that explains how to do it: [http://www.wpbeginner.com/wp-tutorials/how-to-install-wordpress-on-your-windows-computer-using-wamp/](http://www.wpbeginner.com/wp-tutorials/how-to-install-wordpress-on-your-windows-computer-using-wamp/)

 * Thanks for the idea Kerfred but it occurs to me that if this works on my PC (&
   I’m a tad reluctant to try it since the reason I need to migrate away from Joomla
   is because the site has been subject to hacking recently) it won’t tell me what
   is wrong with the server. I wonder if somebody who understands PHP would know
   what is wrong with the PHP settings – there is a page listing these at [http://www.winstred100.org/win100/info.php](http://www.winstred100.org/win100/info.php).

 * Just realised there is an option to test database connection – I even get blank
   screen on this.

 * The server I am on is running MySQL 5.1.73 and on seeing a warning that this 
   version is no longer supported (rather like Joomla 1.5.26), I wondered if this
   might be a problem – does FG Joomla need a specific minimum mySQL or PHP to run?

 * The minimum requirements are MySQL 5.0 and PHP 5.3.

 * So with MySQL 5.1.73, PHP 5.3.27 & Joomla 1.5.26 (stable) this should work. Apart
   from PDO being set up and sufficient memory being available, are there other 
   PHP settings that could cause this problem?

 * One thing you could try is to activate the debug mode in WordPress.
    In wp-config.
   php, add this line: `define('WP_DEBUG', true);` It may give you more details 
   about the error.

 * Ha, thanks – I get this error on testing database connection:
 * Fatal error: Undefined class constant ‘MYSQL_ATTR_INIT_COMMAND’ in /home/winstred/
   public_html/win100/wp-content/plugins/fg-joomla-to-wordpress/admin/class-fg-joomla-

 * The answer is in the FAQ: [https://wordpress.org/plugins/fg-joomla-to-wordpress/faq/](https://wordpress.org/plugins/fg-joomla-to-wordpress/faq/)
 * > You have to enable PDO_MySQL in php.ini on the WordPress host. That means uncomment

 * My webhost had assured me that they had enabled PDO, it seems they had only done
   part of the job. I am now getting somewhere. Thanks.

 * You can check that PDO is enabled by looking at the phpinfo result.
