Hello @webofcreativity,
We sincerely apologize for our delay in responding and for the inconvenience you are experiencing. Since you disabled the Jeg Elementor Kit plugin earlier, the elements/widgets from Jeg Elementor Kit will not be registered. After that, you also saved the page in the Elementor Editor, which caused the Jeg Elementor Kit widgets to disappear. You can try restoring the missing widgets using Elementor’s revision feature.

Regarding the Error 500 you’re experiencing, could you please let us know the configuration of your WP Memory Limit and PHP Memory Limit? You can find this information in the Elementor -> System Info menu.

If your WP Memory Limit is less than or equal to 256MB, we recommend increasing it to 512MB, or even 768MB for better performance. This is also recommended by Elementor itself, as sites with heavy workloads may require a higher WP Memory Limit.

For now, this is all we can suggest. We look forward to hearing back from you.
Thank You
