What code in the WP Sinatra theme generates the words “Read More?”

I’m pulling my hair out. I have searched and searched for a way to remove the “Read More” link from my posts (full post, not excerpt). I’ve tried to add the filter below (and other pieces of code in functions.php) promoted in a number of places on the web. The filter works to turn the excerpt into a full-content post, but the same filter is also supposed to set the Read More text to null. Here’s what I’m using.

/**

  • Redefine sinatra_excerpt function.

*/ function sinatra_excerpt( $ length = null, $ more = null ) { the_content(); }

This function partially works in that it results in showing the full post rather than just an excerpt. it’s just the $ more part that doesn’t work.

For what it’s worth, I have also tried various CSS examples until I’m blue in the face, most utilizing “display:none” on various elements.

I have searched the entire batch of files related to the Sinatra Theme for the string “Read More” and cannot find a single instance of it. If I could find that, I could just replace that with an empty string or otherwise alter the code. Does anyone know where it is?
