350 341 WP-Optimize Cache's Minify feature is all about increasing the speed of your WordPress site for your users.
351 342 One way Minify does this is by reducing the size of your HTML, CSS and JavaScript files by removing unnecessary spaces and lines from the files and shortening long names internally within the code.
352 343 Another way is that your files are merged into as few files as possible. This reduces the amount of load on your web server and can be quicker to load fewer files.

376 367 The first thing to try is to enable the setting "Contain each included file in its own block" in the JavaScript options (WP-Optimize > Minify > Javascript > JavaScript options). This could "catch" an error, and prevent the rest of the code to be broken.
