So called 'infinite upload' never worked well. Usually it loses 5-10% of uploading images. One then need to spot them by numbers and re-upload. That really sucks.

But now I'm getting 'upload failed' message at all files. Error code is 413 (file sizes are more than moderate though - 500-700Kb).

And that is a major sucker. In addition neither Juploadr nor Migratr is working with Zooomr which leaves me locked inside a crippled system.
