Good morning,

Uploading track files cause this error : 

The argument connectionString is null or white space. Parameter name: connectionString

Even former tracks, uploaded in the past will cause this error. 

What am I doing wrong?

Regards

Werner

how do you post? Vi GPSAR, GPSRESULTS or via track upload directly at the website?

Direct Track upload from website with android Samsung S7 and Samsung pda. Same result.
