It’s possible both values in the if statements are empty on the last iteration, causin you to have the empty $title variable. * Thread Starter [seravifer](https://wordpress.org/support/users/seravifer/) * (@seravifer) * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605201) * You were right, thanks. A further problem. When I selected a date returns this error: * ``` Notice: Array to string conversion in \wordpress\wp-content\themes\theme\metabox\includes\CMB2_Utils.php on line 131 Notice: Array to string conversion in \wordpress\wp-content\themes\theme\metabox\includes\CMB2_Utils.php on line 120 ``` * But when I remove the option: `'repeatable' => true` simply is not saved. * Plugin Contributor [Michael Beckwith](https://wordpress.org/support/users/tw2113/) * (@tw2113) * The BenchPresser * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605221) * Could you provide the settings you’re using for this field?

And if you do not use, it is saved when he wants. * I tried on another website and still going the same, with a new theme. * Want to make a video demo?

I’ve been copying what you’ve provided exactly, except for the object type, and just not seeing the error. * As a thought, I’m curious if you’ve somehow got old data for the keys saved, and that’s what’s getting fetched. Have you tried other CMB2 fields using the same key, with this test post you’re using? Or is this happening on a brand new published post? * Thread Starter [seravifer](https://wordpress.org/support/users/seravifer/) * (@seravifer) * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605271) * I’ve been testing and I have not discovered the error. Finally I decided to use jQuery Datapicker. Its works. * Plugin Contributor [Michael Beckwith](https://wordpress.org/support/users/tw2113/) * (@tw2113) * The BenchPresser * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605273) * At this point, do what ya gotta do for a working solution. Wish I knew what was going on with it though, in case it was a bug coming from the plugin itself. * Thread Starter [seravifer](https://wordpress.org/support/users/seravifer/) * (@seravifer) * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605323) * I found the error. Only it appears if you use “dd / mm / yy”. The error occurs when you choose dates where the day is over 12. Example: 6/10/15 choose, beware. 8/13/15 choose, is not saved. * Plugin Contributor [Michael Beckwith](https://wordpress.org/support/users/tw2113/) * (@tw2113) * The BenchPresser * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605324) * Odd, but at the same time if you’re using that format, then the 13 would be the month, not the day, as well. * Thread Starter [seravifer](https://wordpress.org/support/users/seravifer/) * (@seravifer) * [11 years ago](https://wordpress.org/support/topic/show-group-1/#post-6605325) * oh, sorry, yes.
