File Icons don't show up with 'wpdm-all-packages' shortcode

File Icons don’t show up in the jstable with ‘wpdm-all-packages’ shortcode. Please see here.. https://caisafety.com/downloads/

Here is my code:
[wpdm_all_packages items_per_page="50" categories="access-platforms-gangways,bus-rv,overhead-fall-protection" jstable=1 order_by="title" order="ASC" cols="title,file_count,download_count|categories|package_size|download_link" colheads="Title|Categories|File Size|Link" download_link="1"]

I followed the instructions and viewed your demo which shows the file icons, but mine is not.

Hi! thanks for the reply. I cannot give you ftp access as per company policy but I have checked error logs and there is absolutely nothing there.

I tested on another wordpress install and does not work:

I have also checked file-type-icons directory and it is there with the correct permissions.
eg.
https://caisafety.com/wp-content/plugins/download-manager/assets/file-type-icons/pdf.svg

Also, tried sorting by ‘categories’ but does not work. code:
[wpdm_all_packages items_per_page="30" categories="access-platforms-gangways,bus-rv" jstable=1 order_by=”categories” order="ASC" cols="title,file_count,download_count|categories|package_size|download_link" colheads="Title|Categories|File Size|Link" download_link="1"]

I am changing template to one that works [wpdm_category].

You should really fix this for future reference. Thanks!
