Title: PHP Warnings Last modified: February 27, 2024 --- # PHP Warnings * Resolved [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/) * Hi, * This is a strange Warning that appeared WITHOUT touching anything in your widget. I just added a NEW widget from an other plugin and moved it above your’s. * [27-Feb-2024 10:23:38 UTC] PHP Warning: Undefined array key “widget_id” in /home/ public_html/wp-content/plugins/top-10/includes/frontend/widgets/class-posts- widget.php on line 285 * Lines 285, same on 356, 357, 350 , 339, 285 * Thanks Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457637) * Can you try removing the widget and then adding it back in? Remember the configurations when you remove it. The widget_id should exist so it’s quite strange as it’s given an error that it doesn’t. * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457708) * Does it matter if i add it with classic widgets or Gutenberg? * I use classic widgets because i see no option in Gutenberg to change the Title of the widgets, shows “Currently trending:” - This reply was modified 2 years, 3 months ago by [dimal](https://wordpress.org/support/users/dimalifragis/). * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457717) * Both are build differently – the former is the traditional widget. That is what is created by the code above. * The gutenberg one is the block and you might have to add the heading separately etc * I tend to use one or the other on my sites – more the block in recent times. * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457730) * I use classic widgets because i see no option in Gutenberg to change the Title of the widgets, shows “Currently trending:” * i’m missing something? * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457738) * Either way i still get the warnings. They seem to happen only when i move up down. * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457739) * You’ll need to turn off the heading (in block settings panel) and then add your own heading. Then if you right click on both you can group them into a “widget group”. * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457744) * Do the warnings disappear when you save the widgets page and check on the frontend? * I’m wondering if this is a temporary thing that the widget_id is being changed so you get this error. * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457755) * Yes, only once (several for the lines i mentioned), but once i clear them out, i never seen those again if i don’t up/down the widget. * So i’m ok, i guess. I see no other problem. * I use also Widget Context plugin, to display some widgets where i want and where not, maybe that has some relation? * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457826) * I’ll need to test – never used these before. Which is the plugin you are putting up and down and also where are you seeing this error? Screenshot will help as I can go do some checking. * I’ll mark this resolved for now as it does work barring that warning which I’ll need to investigate. * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457860) * Ok, i think i found what is the cause. I added the widget with Classic Widgets enabled (the old widgets WP interface) and then i disabled Classic Widgets and continued with Gutenberg. * Thanks. - This reply was modified 2 years, 3 months ago by [dimal](https://wordpress.org/support/users/dimalifragis/). * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-warnings-183/#post-17457866) * That’s interesting. I think I had to change things with Gutenberg as it didn’t do the typical separate ID etc. But, it has been a while. * Definitely worth pointing to people in case someone else has an issue.
