Title: NPAPI plugins deprecated in Chrome Last modified: August 30, 2016 --- # NPAPI plugins deprecated in Chrome * [kdskd](https://wordpress.org/support/users/kdskd/) * (@kdskd) * [11 years ago](https://wordpress.org/support/topic/npapi-plugins-deprecated-in-chrome/) * When I visit my website in Chrome browser, it gives a popup message that this site uses a plugin with NPAPI, which has been deprecated in the newest versions of Chrome. I want to disable and replace whichever plugin is causing this, but don’t know how to isolate which one it is. The chrome message only shows the first time you visit my site, so I can not simply disable all my plugins and test them one by one to find the culprit. The website is [http://www.quirkbrain.com](http://www.quirkbrain.com). Thank you. * _[ [No bumping please](http://codex.wordpress.org/Forum_Welcome#No_Bumping). ]_ Viewing 3 replies - 1 through 3 (of 3 total) * [unserver](https://wordpress.org/support/users/unserver/) * (@unserver) * [10 years, 10 months ago](https://wordpress.org/support/topic/npapi-plugins-deprecated-in-chrome/#post-6211718) * I have the same problem, eventually you find the solution? * [Tim McGuinness](https://wordpress.org/support/users/perfectreputationsnowadmin/) * (@perfectreputationsnowadmin) * [10 years, 6 months ago](https://wordpress.org/support/topic/npapi-plugins-deprecated-in-chrome/#post-6211743) * If this is Chrome disabling Java altogether, then the WP architecture may be the problem, there is Java throughout. * For now, it is only a one time message. And I tell my clients to refresh. * However, we are also going through every function of our sites looking for what was disabled. This is a horrific task. It could take more than a week per site just to review. * We need an immediate guidance from Automatic and the WP dev community now!!!! * [Tim McGuinness](https://wordpress.org/support/users/perfectreputationsnowadmin/) * (@perfectreputationsnowadmin) * [10 years ago](https://wordpress.org/support/topic/npapi-plugins-deprecated-in-chrome/#post-6211761) * For any that find this error in Chrome, the solution took months to discover. * It turns out that Kasperski Password Manager it at fault. * When you install and activate the KPM in the browser, and then edit WordPress pages, it installs this string in your pages: *
* WTF! Why would Kasperski install what is in effect a viral string in your WP documents? No idea, but there it was. * To resolve this requires the following: 1) uninstall this crap password manager from your Windows computer – you can keep the anti-virus, but get rip of the password manager (use LastPass instead); 2) remove the KPM extension in all of your browsers; 3) make sure that your WP site has JetPack installed and Omnisearch enabled – use it to search fro “KPMPlugin” – then edit each page or post in TEXT mode and remove/delete the code string above for each page or post. * This solves the problem. * Except, if you edited the source of any theme or plugin, you need to check for this addition in those files too! * As a WordPress professional, you need to eradicate the Kasperski Password Manager from every computer you, your team, and your clients use. * This was a monster. Kasp[erski owes me a few years of their service to repay me for this screw up!
