I am getting an error while saving table data and the error is PHP Fatalerror: Uncaught Error: Call to undefined method WP_Optimize::get_page_cache() in /nas/content/live/carlisleitdev/wp-content/plugins/tablepress/models/model-table.php:687

This error happens during the cache clearing of the WP Optimize plugin that TablePress does here. From what I can see, TablePress uses the mechanism from the WP Optimize Documentation.
Therefore, I assume that something with your WP Optimize plugin is wrong. Can you please check if you are using the latest version, and can you please try re-installing it from a fresh download, to rule out missing/corrupted files in it?
