help me please

Operation look in the code on the left side at the bottom: there must be a line like:
<script src="<?php echo document::href_rlink(FS_DIR_TEMPLATE . 'js/app.min.js'); ?>"></script>
If you have per example a line like:
<script src="<?php echo document::href_rlink(FS_DIR_TEMPLATE . 'js/app.js'); ?>"></script>
then you must change on the right side under Operation 1: [b]app.min.js[/b] to [b]app.js [/b]and then save

Second option: Operation 1 find: change 
<script src="<?php echo document::href_rlink(FS_DIR_TEMPLATE . 'js/app.min.js'); ?>"></script>
to 
</body>

and change Method: [b]afte[/b]r to method:[b] before[/b]

Thank you
