Error on upload file too large

Just a bit of feedback – I attempted to upload a file larger than allowed in my php.ini file, and no warning or error condition arises. Had I looked at the list of files, I would have seen the missing download link info though. But I first became aware of the problem when using the shortcode to display a library’s contents, seeing the following error messages:
Notice: Undefined offset: 0 in …/filr-protection/src/class-filr-shortcode.php on line 257 also same message for lines 259, 260 & 261.
Maybe some error checking on the file upload process would cover this problem & other upload failures too.
