Any ideas (apart from switching debug off)! * Cheers - This topic was modified 2 years ago by [funkygorilla](https://wordpress.org/support/users/funkygorilla/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-error-showing-in-wordpress-debug%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 14 replies - 1 through 14 (of 14 total) * [mauskino](https://wordpress.org/support/users/mauskino/) * (@mauskino) * [2 years ago](https://wordpress.org/support/topic/php-error-showing-in-wordpress-debug/#post-17748900) * Hi!

I thought it was a plugin conflict, but just installed the plugin on a site with no other plugins, and the error displays regardless of what theme I select. * [LoreGI13](https://wordpress.org/support/users/loregi13/) * (@loregi13) * [2 years ago](https://wordpress.org/support/topic/php-error-showing-in-wordpress-debug/#post-17751672) * yes [@harbormark](https://wordpress.org/support/users/harbormark/) , you’re right, there is an error they should fix in the new version of the plug-in: it appeared since the last update, 2 days ago. Is there a way to report the issue to the developers? * [Hudson Phillips](https://wordpress.org/support/users/harbormark/) * (@harbormark) * [2 years ago](https://wordpress.org/support/topic/php-error-showing-in-wordpress-debug/#post-17751686) * [@loregi13](https://wordpress.org/support/users/loregi13/) I have no idea how to get them to know other than here. I’m using the free plugin so no priority for me. I noticed the error a few days ago and hoped there would have been a fix available already. * The error is visible on multiple sites and I’m hoping it’s patched soon so I don’t have to find an alternative plugin 🙁 * Thread Starter [funkygorilla](https://wordpress.org/support/users/funkygorilla/) * (@funkygorilla) * [2 years ago](https://wordpress.org/support/topic/php-error-showing-in-wordpress-debug/#post-17752598) * I can confirm that if you switch off error reporting on the front end of the site in wp-config.php, you don’t see this error. Having said that, just because we can’t see it doesn’t mean it’s gone away!

How can I downgrade to 3.3.3? * Any suggestions? * Kind regards, Jan * [mauskino](https://wordpress.org/support/users/mauskino/) * (@mauskino) * [2 years ago](https://wordpress.org/support/topic/php-error-showing-in-wordpress-debug/#post-17753040) * I can confirm that this workaround works (although it doesn’t solve the initial problem).
