Do you have a duplicated copy of the plugin in there? Was anything else installed or updated? That’s the only thing I can think of.
thanks,
Is there a solution for that issue? I have the same problem and i can say that there is no duplicate folder of Sucuri Security. This is a new installation. My WP version is 4.6. I have scanned the whole installation (htdoc directory) for the class definition. The result was: `grep -R SucuriScanSiteCheck *
wp-content/plugins/sucuri-scanner/sucuri.php: && SucuriScanSiteCheck::isDisabled()
wp-content/plugins/sucuri-scanner/sucuri.php: && SucuriScanSiteCheck::isDisabled()
wp-content/plugins/sucuri-scanner/sucuri.php: $params[‘Settings.SiteCheckStatus’] = SucuriScanSiteCheck::statusPage();
wp-content/plugins/sucuri-scanner/sucuri.php: $params[‘Settings.SiteCheckCache’] = SucuriScanSiteCheck::cachePage($nonce);
wp-content/plugins/sucuri-scanner/sucuri.php: $params[‘Settings.SiteCheckTimeout’] = SucuriScanSiteCheck::timeoutPage($nonce);
wp-content/plugins/sucuri-scanner/sucuri.php:class SucuriScanSiteCheck extends SucuriScanSettings
wp-content/plugins/sucuri-scanner/sucuri.php: if (SucuriScanSiteCheck::isDisabled()) {
`
Can confirm the issue is xcache on PHP. Have you enabled it recently?
I also encounter the issue, but after upgrading WordPress to 4.6.1 and subsequently Sucuri to 1.8.1 – xcache settings were not changed. Do you have a workaround?
I moved my wordpress installation to new domain , now i get this error
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare class SucuriScanSiteCheck in /var/www/clients/client0/web1/web/wp-content/plugins/sucuri-scanner/sucuri.php on line 13555
