Let me reinstall old plugin and see what happens. * Thread Starter [JJNW](https://wordpress.org/support/users/jjnw/) * (@jjnw) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12710659) * Same issue.

The information you have shared so far doesn’t say a lot to me. You’ll need to share more info (like reproduction steps, screenshots, etc) so I can help. * Thread Starter [JJNW](https://wordpress.org/support/users/jjnw/) * (@jjnw) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12710755) * Okay, here are the steps. * Install, activate, default settings (in settings page, Tools). * Go to Appearance > Widgets place widget in widget area. * Un-select show views (counts) – Save button = the checkbox comes back. * Go to front-end, that where you’ll see error too (without wp-config show WP errors enabled). * I am using Kleo theme. * I’m gonna need to chase down plugin conflicts too. * Thanks. * Plugin Author [Hector Cabrera](https://wordpress.org/support/users/hcabrera/) * (@hcabrera) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12710960) * Followed your instructions on a new WordPress setup and couldn’t reproduce the issue (no other plugins active, stock Twenty Twenty theme). The widget was able to save the settings normally. * ![Drag-and-drop of the WPP widget into a sidebar, options saving normally as expected](https://i0.wp.com/i.postimg.cc/k4Qv6dZS/drag-and-drop-wpp-widget-in- admin-area.gif?ssl=1) * Checked the debug.log file as well and it’s clean, no PHP notice/warning/error messages were logged by WordPress. * Try using the [Troubleshooting mode](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/) and see if it tells you anything. * Thread Starter [JJNW](https://wordpress.org/support/users/jjnw/) * (@jjnw) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12710989) * Yup – not your plugin! * Its Content Control Plugin conflicting with it. `https://wordpress.org/plugins/ content-control/` * Both are great plugins – yours obviously wins this battle for Seattle. * Thank you for your help and patience. * All’s good in la hood. * AWESOME PLUGIN. * Plugin Author [Hector Cabrera](https://wordpress.org/support/users/hcabrera/) * (@hcabrera) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12711010) * Awesome, thanks for the heads-up! * I’ll see if I can find some spare time to check out that plugin you mentioned and maybe figure out what’s going on. I’m sure its developer would want to know about this issue as well. If so, I’ll make sure to leave a comment here to keep you (and anyone reading this) updated. * Anyways, thanks for the kind words. I’m glad you like my plugin! * Thread Starter [JJNW](https://wordpress.org/support/users/jjnw/) * (@jjnw) * [6 years, 1 month ago](https://wordpress.org/support/topic/warning-php-warning-explode-expects-parameter-2-to-be-string/#post-12711018) * Like? I think love is more descriptive Ahahah * Seriously, awesome. * Thanks, and I hope the other developer can help out.
