 * I just installed the spam blocker and added some domains to block. When I save
   the form, I get the following errors (I’ve replaced the hosting location with
   <site> to make it easier to read):
 * **Warning**: Undefined array key “wpcf7_block_log_erase” in **<site>**/wp-content/
   plugins/wp-contact-form-7-spam-blocker/admin/class-admin.php on line **274**
   **
   Warning**: Undefined array key “request-form-path” in **<site>/wp-content/plugins/
   wp-contact-form-7-spam-blocker/admin/class-admin.php** on line **288****Warning**:
   Cannot modify header information – headers already sent by (output started at
   <site>/wp-content/plugins/wp-contact-form-7-spam-blocker/admin/class-admin.php:
   274) in **<site>**/wp-includes/pluggable.php on line **1435**
 * My changes were saved, but the form did not block the email domains during my
   test.
 * How do I fix these errors?
 * Thank you.

 * Hi,
 * You cannot use <site> as part of the filename.
 * Please uninstall and reinstall the plugin.
 * Follow the detailed instructions you find under each field, save the Contact 
   form 7 setting and test.
 * Thanks,
 * NYSL
