PDF link intermittently throws error

When clicking on various document links an error is thrown intermittently. See attached screen shot.

Warning: A non-numeric value encountered in ..\wp-content\plugins\download-manager\libs\class.DownloadStats.php on line 35

My apologies for not responding right away, but your emails were going to my junk folder.

I repaired the issue by changing line 35 of class.DownloadStats.php.

From this: $udl[“{$index}”] = isset($udl[“{$index}”])?$udl[“{$index}”]+1:1;

To this: $udl[“”.$index] = isset( $udl[“”.$index] ) && is_numeric( $udl[“”.$index] ) ? $udl[“”.$index]+1 : 1;

Hopefully this will be fixed in the next update.

To anyone reading this. A version update provided a fix for this, as well.
