# [Plugin: Backup] Fatal error when activating plugin

 * Excited to try out this plugin.
    When I install by downloading the plugin (Version:
   1.1.4), I get an error. When I try to install via the WP install new plugin, 
   it just stalls out.
 * Here is the error:
 * > Plugin could not be activated because it triggered a fatal error.
   > Please load the ‘zip’ PHP extension. It is needed in order to create the archive
   > to be backed up.
   > Fatal error: Could not activate Backup. in (full prefix of path on server removed)/
   > hv4/wp-content/plugins/backup/backup.php on line 59
 * Could this be due to the fact I am developing the site in a subdirectory?

 * Hi,
 * You need to install the php-zip extension for the plugin to work.
 * The process is different depending on the operating system you use. Just google
   it and you should have no problem finding how to install it.

 * HI,
 * My hosting provider asked if this backup plugin can also be made to work with
   Zlib too? I get the ‘zip’ PHP error when I try to install now.
