Error after integrate with adminlte

For one your loading jQuery twice, once for AdminLTE and then your loading it again
for Grocery CRUD. So you are over writing the first jQuery with an older version.

I would download the newest jQuery version 3.3.1 and just use it.

thank you very much for your answer but 2nd "load" 

PHP Code:

<!--
GROCERY CRUD
<script src="<?php echo base_url();?>assets/grocery_crud/js/jquery-1.11.1.min.js"></script>
--> 


is really necesary update JQUERY? do you think that will solve all problems?
this code without adminlte works fine

and JQUERY version loaded is that one comes with adminlte template
