Fatal error: Failed opening ...app/lib-autoload.php

Hi there,

I’ve had this Sage 9 site in development for the last few days and all has been running smoothly. Suddenly, after adding a line of javascript this morning, I now have this error which I’m not sure how to resolve.

Any help would be appreciated!

Fatal error: require(): Failed opening required ‘/Users/kate/Sites/northern.academy/wp-content/themes/sage-new/vendor/composer/…/…/app/lib-autoload.php’ (include_path=’.:/Applications/MAMP/bin/php/php7.0.15/lib/php’) in /Users/kate/Sites/northern.academy/wp-content/themes/sage-new/vendor/composer/autoload_real.php on line 66
