Title: Problems after upgrading Elementor Last modified: March 24, 2022 --- # Problems after upgrading Elementor * [bytecanarias](https://wordpress.org/support/users/bytecanarias/) * (@bytecanarias) * [4 years, 2 months ago](https://wordpress.org/support/topic/problems-after-upgrading-elementor/) * Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site and notifies you via this automatic email. * In this case, WordPress has detected an error with one of your plugins, Charts and Graphs for Elementor.

I received the notification from WordPress about three hours after toggling all of my plugins to determine why Elementor was responsive on only a handful of pages. * From the human experience side: on some pages I was able to make one or two edits then the widgets would grey out and I was unable to save (it seems that auto- save still worked.) * [Ash](https://wordpress.org/support/users/ashbryant/) * (@ashbryant) * [4 years, 1 month ago](https://wordpress.org/support/topic/problems-after-upgrading-elementor/#post-15559936) * I’ve had the same issues. * I think this plugin is relying on some deprecated functions in Elementor, therefore you need to replace all instances of “use Elementor\Scheme_Typography;” with “ use Elementor\Core\Schemes\Typography;” and change all “Scheme_Typography::” to “Typography::” * Same for Scheme_Color. * See [https://developers.elementor.com/v3-0-planned-deprecations/](https://developers.elementor.com/v3-0-planned-deprecations/) - This reply was modified 4 years, 1 month ago by [Ash](https://wordpress.org/support/users/ashbryant/). * [bcobin](https://wordpress.org/support/users/bcobin/) * (@bcobin) * [4 years, 1 month ago](https://wordpress.org/support/topic/problems-after-upgrading-elementor/#post-15564213) * Same error. Please advise when there’s a working version. Note that I had to deactivate the plugin to get the site to work, so the usual upgrade procedure won’t work – please advise.

I guess we still need a true update from the developer of the plugin.
