.js files references, but missing

I just started to receive these messages:

• Warning: file_get_contents(sites/all/themes/eventus/assets/scripts/evolve.js): failed to open stream: No such file or directory in drupal_build_js_cache() (line 5111 of /srv/bindings/8ed79a572c8e4e86a7c6726389722fcc/code/includes/common.inc).
• Warning: file_get_contents(sites/all/themes/eventus/assets/scripts/custom.js): failed to open stream: No such file or directory in drupal_build_js_cache() (line 5111 of /srv/bindings/8ed79a572c8e4e86a7c6726389722fcc/code/includes/common.inc).

Any help in eliminating the errors?
