 * Hi.
 * I’m getting the following error message when I try to access my website.
 * Fatal error: Declaration of wfWAFAttackDataStorageFileEngineResultSet::scanRow(
   $handle, $offset, $length) must be compatible with wfWAFAttackDataStorageFileEngineScanRowCallback::
   scanRow($handle, unknown &$offset, $length) in /home1/ingriman/public_html/wp-
   content/plugins/wordfence/vendor/wordfence/wf-waf/src/lib/storage/file.php on
   line 1178
 * Any idea what’s causing this?
 * Thank you.

 * Hi,
    Could you please confirm you are using the latest version of Wordfence (
   which is 6.3.8 by now)? also, which version of PHP your server is running?
 * Thanks.

 * Hi,
 * Thank you for the response. No worries though. I didn’t do anything, but it’s
   working fine now. Must have been a hiccup on the hosting side.
 * Wordfence version is 6.3.8 and PHP is 7.0.
 * THANK YOU.
