    Hello!

    I am using the Mailchimp connection on a lot of different points on my page, and so fare everything went perfect.

    I embed a form on my “newsletter” side.

    I instated Bozilla to get an popup to. I used the same form as an the “newsletter” page. but know it is not working anymore. if i try to syn me up, either on the newsletter page or on the pop up i get this error massage:

    Warning: trim() expects parameter 1 to be string, array given in /home/.sites/8/site1663006/web/wp-content/plugins/mailchimp-for-wp/includes/class-field-formatter.php on line 51

    I removed the file from the popup again, but is is still not working on the newsletter page: https://www.nimbi.at/ueber-nimbi/newsletter

    Is is possible the use one form me then one times?

    How can i solve this problem?

    Thank you so much!!!
    Ingrid

    Hi Ingrid,

    This is a known warning in the current version of the plugin. It’s not harfmul as it is, but we’ll be releasing an update that fixes this later this week.

    Please know hoever that your site is showing “PHP warnings” where it really shouldn’t – this gives hackers information about the application your site is running. I would contact your host and tell them to disable error reporting for your live site, this is really only something that should occur on development servers.

    Hope that helps. If not, let me know!

    For us it is a breaking error.

    Line 51 tries to trim a variable. Some lines later there is a check if the variable is an array (so it seems likely that the variable is an array – some of the times).
    I am quite sure that the script breaks if the variable is an array – as trim is not built for arrays.

    Quick fix: wrap line 51 in an if-statement.
    Replace line 51 with: 

    if ( is_string( $value ) ) {
      $value = trim( $value );
 }
