Cannot reinitialise DataTable

Hi,
plugin worked fine until I got this error:

DataTables warning: table id=wpdmmydls-c2f54b1292907baa81f09f1c865ad2e5 – Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3

and search and sorting is missing on the public page

My shortcode is
[wpdm_all_packages categories="XXXXX" jstable=1 order_by="publish_date" items_per_page="20" order="DESC" cols="title,file_count,download_count|publish_date|download_link" colheads="Title|Date|Download"]  

Any suggestion, please?

Thanks for replying so fast, but I have ONE single table in the page

Yes, because the error appears in the backend

Thanks.
I think I solved: it was a conflict with Jetpack Boost plugin.
A cache problem, maybe.

I deactivated the plugin and search and sorting now are displayed
