The Raven plugin fix is available in the Jupiter X -> Control Panel -> Plugins. Please ensure you update Raven first and then update the Elementor to 2.4.1
For the users whose site is still crashed, you can access your site files through FTP and remove both Elementor and Raven plugin files. Then go to Jupiter X -> Control Panel -> Plugins and activate the Elementor and then the Raven plugin.
This is regarding the Jupiter X + Elementor 2.4 + Raven that crashes the site and shows a fatal error.
As some of might you have already experienced this issue, we are aware of this issue too and we are working on it to fix it.
In the meantime, please downgrade the Elementor to the previous version which is 2.3.8.
There are 2 ways to do it:
1 - This is a bit easy way to handle this issue. Please access your site using FTP, then go to wp-content/plugins folder and remove the Raven plugin folder. Once you delete this folder, the fatal error will go away and you will be able to access your site again.
Then, go to admin panel and access Elementor -> Tools -> Version Control and rollback to the previous version which is 2.3.8 in our case.
Now, go to Jupiter X -> Control Panel -> Plugins and activate the Raven Plugin.
2 - You can do this by accessing your site using FTP, then go to wp-content/plugins folder and remove the elementor folder. Once you delete this folder, the fatal error will go away and you will be able to access your site again. The site may be in bad shape though but don’t worry.
Now, download the version 2.3.8 from this dropbox link https://www.dropbox.com/s/i3hsqothk5jyekk/elementor.2.3.8.zip?dl=0
Extract the zip file and again go to wp-content/plugins folder and paste the plugin files in this folder.
