 * Hi there,
 * We have been using this plugin for several months now. However for the past 2
   days, we have been experiencing some issues with this. Perhaps something changed
   and the plugin is not siting well with our website. Hoping someone here can help.
 * When we try and activate the plugin (1.8.1 version) this is the error we get:
 * Fatal error: require_once(): Failed opening required ‘/home/CPANELUSER/public_html/
   <WEBSITE>/wp-content/plugins/wpematico/app/campaigns_edit.php’ (include_path=’.:/
   opt/cpanel/ea-php71/root/usr/share/pear’) in /home/CPANELUSER/public_html/<WEBSITE
   >/wp-content/plugins/wpematico/wpematico.php on line 66
 * It’s not a permissions issue, though.
 * By the way, when we reverted back to the older version of the plugin (version
   1.7.3) everything seems to be working fine!
 * Thanks y’all!

 * Hi [@txsuperstar](https://wordpress.org/support/users/txsuperstar/),
 * Sounds like you do not updated all the files of the plugin.
 * Try to rename or delete the old wpematico directory and install again the new
   wpematico plugin.
 * regards
