Webpage server actions are not connecting with the server

It appears as though I have connection with my database (i.e. I can view and edit my tables and I can create API server actions such as queries, inserts, etc just fine. However when I try to execute the server actions through my webpages, nothing happens. I’ve tried to do a form submission with ON SUCCESS and ON ERROR notification messages and no notifications are displayed on submission of the form. I tried to do a simple query to display data on the page and nothing is retrieved. I’m using BS5 with PHP server model. This is a new site so this is the first time I’m connecting with the database and executing server actions. Please help!
