I too have experienced problems on both staging & production sites with two remedies…deactivate your plugin, or revert to back-up with previous version of Elementor. * Kind Regards, Evan * [zebrawebdesigns](https://wordpress.org/support/users/sbhuvan/) * (@sbhuvan) * [4 years ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15510488) * [@generactevan](https://wordpress.org/support/users/generactevan/) Hi No I am not the plugin developer and the fix I give will make the plugin work.

We need this to be fixed asap! Our clients cannot download our guides. This is a serious problem and we need help with it. * Thread Starter [eyeswiseopen](https://wordpress.org/support/users/eyeswiseopen/) * (@eyeswiseopen) * [4 years ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15523945) * My solution: deleted this plugin install Premium Addons for Elementor it has a modal widget that does the same and can be triggered by a button no need for separate post for the popup it is all in the widget. * I used this plugin on a number of sites – luckily in most cases it was in a template so only had to change it in one place. * [saharch](https://wordpress.org/support/users/saharch/) * (@saharch) * [4 years ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15523991) * Ok, thanks. Meanwhile, I tried restoring to an earlier backup with Updraft Plus and just crashed my entire site. So bigger problems to deal with now. * [zebrawebdesigns](https://wordpress.org/support/users/sbhuvan/) * (@sbhuvan) * [4 years ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15524109) * [@saharch](https://wordpress.org/support/users/saharch/) I am not sure if I can share my personal details here.

That was a very good solution. * [weiswerks](https://wordpress.org/support/users/mwbarican/) * (@mwbarican) * [4 years ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15533143) * For anyone experiencing the same issue, I was able to fix it by changing the scheme values on line 185 from: * `'scheme' => Scheme_Typography::TYPOGRAPHY_4,` * to: * `'scheme' => \Elementor\Core\Schemes\Typography::TYPOGRAPHY_4,` * same as Scheme_Color on line 446 from: * ``` 'type' => Scheme_Color::get_type(), 'value' => Scheme_Color::COLOR_4, ``` * to: * ``` 'type' => \Elementor\Core\Schemes\Color::get_type(), 'value' => \Elementor\Core\Schemes\Color::COLOR_1, ``` * [macrorxplus](https://wordpress.org/support/users/macrorxplus/) * (@macrorxplus) * [3 years, 12 months ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15551454) * [@mwbarican](https://wordpress.org/support/users/mwbarican/) does seem to fix the issue – This is in the file popup.php * I also found an instance in popup-load.php on line 191 that I would recommend making the same change to Scheme_Typography * [Eileen_Cecelia](https://wordpress.org/support/users/eileen_cecelia/) * (@eileen_cecelia) * [3 years, 12 months ago](https://wordpress.org/support/topic/plugin-creates-critical-error/#post-15560374) * None of the suggested fixes worked for me.
