If you check the details you’ll find that the vulnerabilities mentioned are found in versions of the plugin earlier than the current one. Just make sure to keep all your plugins updated as an extra defense.

Thanks for getting to the root of this so quickly. Really like your plugin!

Great. Maybe that’s all it takes?

I also had the white-screen result with 5.3. I deactivated the plugin and left it that way while gone for a few hours. On reactivation the problem has gone away, and still seems functioning fine. Plugin cache? Browser cache?

If you want to try again with it, just rename it back to the original and re-activate it in admin > plugins. If it is still broken, disable it again as you did before, and open a thread in the support forum for the plugin and include the error message:

Warning: Cannot modify header information – headers already sent by (output started at /home/titlihc/public_html/wp-content/plugins/search-keyword-statistics/admin.php:80) in /home/titlihc/public_html/wp-includes/pluggable.php on line 1207

There is another thread there already with the same issue, but they claim it isn’t the fault of their plugin. Your message doesn’t point to another plugin, only theirs (if you posted the entire message above).

Joyce and CGardikiotis: please open your own threads for each of your issues. The original poster has finished with this thread, and your issues are almost certainly not identical to the original, or even each others. You deserve your own threads for your issues. ??

You’re welcome, and good luck!

Glad you got this worked out!

There’s no harm in trying again with a child theme, now that you know how to back out if you need to. That’s the beauty of child themes. Most likely there was an error in the PHP since, as questas_admin said above, that’s usually what takes a site down. CSS errors usually just mess up visual presentation.

Please mark this thread as resolved if you would. And, you’re welcome!

If you can’t access your admin pages, you’ll need to use an FTP client (like FileZilla), or your host’s cpanel (or File Manager) and navigate to the files on the server.

In your WP installation there, find wp-content/plugins/search-keyword-statistics and rename that plugin’s folder to something like search-keyword-statistics-hold. That will disable it and hopefully allow you to get back into WP admin.

Don’t forget to first clear your browser cache and cookies before trying to log in again.

edit: ooh, by two seconds!

Try switching to the Twenty Fifteen theme and see if the content comes back. If so, delete and re-install your Twenty Fourteen theme. Your page says that it’s not finding some javascript that should be included in the theme.

EDIT: If you have made modifications, save a copy of it before deleting it from the server.

Did you create a child theme as those instructions directed? And did you add that code to the child theme? If so, you can just delete the child theme and go back to using the parent theme.

If you can’t access your admin pages, you’ll need to use an FTP client (like FileZilla), or your host’s cpanel (or File Manager) and navigate to the files on the server.

In your WP installation there, find wp-content/themes and delete only the child theme folder (not ‘themes’ or customizr). That will hopefully allow you to get back into WP admin where you can activate your theme.

You’re welcome. Good luck!

Try re-saving your permalink settings at Settings > Permalinks. That often will fix it right up.

Best idea is to ask about this in the support forum for the add-on and/or WooCommerce forum.

You might just hide it with something like this in your custom css:

.site-info {
    display: none;
}

Otherwise you need to create a child theme and make changes there.
