# blank page running installer.php

 * I’ve been using Duplicator for a couple of years now and it is by far my favourite
   plugin. However it’s suddenly stopped working. I create a new package on my localhost
   server with no problem and I can ftp the zip file and installer.php up to the
   remote server just fine.
 * But when I visit installer.php in chrome, whilst it finds the page, it’s just
   blank. There’s no source html. I asked my host (who run php 5.3.3) to examine
   their server log files they get the following error:
 * PHP Parse Error: Syntax error, unexpected T_IF, expecting T_FUNCTION installer.
   php line 316.
 * Any help gratefully received. I’m running latest version of Duplicator.

 * Hey Kevleitch,
 * It looks like you may have a corrupted installer file. Did you FTP directly from
   your wp-snapshots folder on your localhost or did you happen to download it from
   the Packages screen?
 * Cheers~

 * Hi Cory, thanks for the reply.
 * I tried it both ways. Downloading from within WP Admin and then FTPing down from
   wp-snapshots. Both ways give the same result – just a blank page. I’ve also tried
   creating a new package but I get the same – just a blank page.
 * Thanks.

 * Maybe try and create another package… If the problem is consistently repeatable,
   then you can submit a ticket and I’ll have a look at it…

 * Well now things have gone very odd.
 * I tried uninstalling Duplicator via WP Admin, then deleting the directory completely
   and then reinstalling it. Now I can create a package with a perfect scan result,
   download both zip and installer.php and yes, once uploaded via FTP, installer.
   php now works!
 * Sadly, I now have a new issue. When I run the installer I get thousands of deploy
   errors. Upon checking the installer log I have various database errors, from 
   SQL syntax errors to non existent table names. Here’s a couple of examples:
 * ‘**ERROR** database error write ‘Table ‘devboxlabcouk_aa.wpoknle_ac’ doesn’t 
   exist’ – [sql=INSERT INTO `wpoknle_ac` VALUES(“139”, “cms_tpv_settiio”, “0.8.13”,“
   yes”)…]’
 * and
 * ‘**ERROR** database error write ‘You have an error in your SQL syntax; check 
   the manual that corresponds to your MySQL server version for the right syntax
   to use near ‘menu-top\”:\”TTQwLrole_access\6;s:8on\”;i:5;s:6:\”parent\”;N;s:9:\”
   css_class\”;N’ at line 1′ – [sql=INSERT INTO `wp_options` VALUES(“136”, “ws_menu_editor”,“
   a:14:{s:22:\”hide…]’
 * I’d like to reiterate that this website works perfectly on my WAMP driven localhost.
   Once again, any help very gratefully received.
 * EDIT: If you need to see the whole installer log, let me know and I’ll mail it
   to you.
 * Thanks

 * You probably have an incompatibility between your MySQL versions. You might try
   the mysqldump from the settings page to see if that works SQL script that is 
   generated works…
