 * I’m not sure if this is the same issue, but I received a 500 error after updating
   from 6.7.5 to version 7.7. Admin and public pages all gave 500 errors.
 * I deleted the plugin via FTP and the site was restored. I tried to reinstall 
   Cerber and was unable to activate plugin. Here’s the error message:
    Parse error:
   syntax error, unexpected ‘[‘ in …..wp-content/plugins/wp-cerber/common.php on
   line 1970
 * Noticed the PHP version was 5.3.3. Updated PHP to 5.6.30. I was able to successfully
   install 7.7. No error message and the site looks good.

 * Hi,
 * Upgrade to version 7.7.
 * Edit line 1970 of wp-content/plugins/wp-cerber/common.php and change
    headers
   = []; to headers = array();
 * Hit the reload button of your browser and all will be fine,.
 * Regards from Britanny.

 * Please do some homework before posting a support request. Check the Activity 
   tab. In most cases, you find the answer there. Go to the Traffic Inspector page,
   click Suspicious activity. Most likely your web server is misconfigured or you
   use poorly designed plugin to restrict downloads.
