I keep getting this error message for my site farbratten-zucht.de . I haven´t changed anything, so I am surprised to suddenly get this message

Hey @kathringuttmann,

That doesn’t seem to be coming from our theme because if that is the case, we’ll also get the same error in our site. Remember that a theme is only a part of WordPress so some parts of WordPress like 3rd party plugins could be causing that.

Please first do the following basic troubleshooting procedures related to your issue to narrow down what’s causing it.

1. TESTING FOR THEME RELATED ISSUE
2. TESTING FOR PLUGIN CONFLICT
3. THEME UPDATE
4. CHILD THEME
5. CSS/JS CUSTOMIZATION

If the message doesn’t create trouble in your site but just to display the error, you can disable the display of warnings in your site. If fact, it’s recommended for live sites. Please follow WordPress debugging recommendation here: https://wordpress.org/support/article/debugging-in-wordpress/

Only if none of the suggested solution helps and you’re sure it’s an issue with our theme and not by 3rd party factors, please give us the following information in a Secure Note

• WordPress Login URL
• Admin level username and password
• FTP access

You can find the Secure Note button at the bottom of your posts.

Thanks.
