Hello @alexandraalegria,
We aren’t able to see what’s happening with your admin section because we cannot log in to your site. Could you please share a screenshot of what you see on https://alexandraalegria.com/wp-admin/post.php?post=1168&action=elementor? You can use an app like https://snipboard.io/ if you don’t already know of another method.
For issues like this, there is often a plugin or theme conflict.
Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If you can install plugins, install and activate Health Check: https://ww.wp.xz.cn/plugins/health-check/
It will add a new feature under Tools > Site Health.
On its Troubleshooting tab, you can Enable Troubleshooting Mode. This will disable all plugins, switch to a standard WordPress theme (if available), allow you to turn your plugins on and off, and switch between themes, without affecting normal visitors to your site. This allows you to test for various compatibility issues.
There’s a more detailed description about how to use the Health Check plugin and its Troubleshooting Mode at https://make.ww.wp.xz.cn/support/handbook/appendix/troubleshooting-using-the-health-check/.
