 * Hi!
 * I changed some Yoast SEO settings, then tried to SAVE, but unfortunately I get
   an error message:
   Oh nein! Scheinbar enthält dein Formular ungültige Daten. Bitte
   überprüfe folgende Felder: [Templates – Bild für Social-Media](https://www.stromboli.at/wp-admin/admin.php?page=wpseo_page_settings#/post-type/template-item#button-wpseo_titles-social-image-template-preview):
   wpseo_titles.social-image-id-template must be a `number` type, but the final 
   value was: `NaN` (cast from the value `false`).
 * When I switch to “Templates”, I get:
   Etwas ist schief gelaufen. Ein unerwarteter
   Fehler ist aufgetreten.Es tut uns sehr leid, aber anscheinend hat der folgende
   Fehler unsere Anwendung angehalten:**e.match is not a function**
 * Pls. see the attached screenshots as well:

 * Hello [@webmark487](https://wordpress.org/support/users/webmark487/),
 * Thanks for reaching out. Often, we see problems occur in combination with another
   plugin or theme. The fastest way to rule out any conflict is to **deactivate 
   all non-Yoast plugins and switch to a standard theme** like [Twenty Twenty-Two](https://wordpress.org/themes/twentytwentytwo/).
 * Please test this on your development or staging site if you have one. If not,
   we recommend using the [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/)
   plugin. This plugin has a troubleshooting mode, which **does not affect normal
   visitors to your site**.
 * If you’re unfamiliar with checking for conflicts, we’d like to point you to a
   step-by-step guide that will walk you through the process: [How to check for plugin conflicts](https://yoast.com/help/how-to-check-for-plugin-conflicts/)
 * If you feel uncomfortable doing this yourself or if this does not solve your 
   issue, our [Yoast SEO Premium plugin](https://yoast.com/wordpress/plugins/seo/)
   comes with one year of (technical) support.

 * I tried a lot, for example I checked for plugin conflicts and used the Health
   Check & Troubleshooting plugin.
 * Finally I did all the updates.
   And finished the basic setup of Yoast SEO, and
   then the settings could suddenly be saved.
 * So I don´t know, what the problem was. But it finally works now …
 * Thank you for your support!
