Hi There @janaroberts
I have enabled WP_DEBUG mode on your site as mentioned on this guide (https://codex.wordpress.org/WP_DEBUG) and then when I visit your MEC Settings page, I see the following error (see secure note below).
To re-install your plugin without losing your data, please download all files from your Themeforest downloads.
Then when you unzip the file, you should be able to locate “modern-events-calendar.zip” file under extensions directory. You need to then extract “modern-events-calendar.zip” and upload it into your (/wp-content/plugins/) section and it will replace any missing or corrupted files.
Hope that helps.
