I am trying to update the settings page but cannot click or highlight any characters on the settings page. The sub tabs do not work and cannot click on any fields. I have tried deactivating the plugin and reactivating it but nothing. Any ideas what could be causing this. I have Premier 5.1, Store Locator Plus 5.0.5 and Power 5.0.4. Also using WordPress 5.1 and PHP 7.2.15 and MySQL 5.5.62.
