Hello, dear member of forum.
I (very hard) upgrade modx, extensions,php,mysql from versions of 2015 year to latest.
After clearing a bunch of bugs i make my website working againg.
But multyupload still do not works (all was working fine, i just made multyupload as described in rtfm).
Now, when i press "upload files" button, i see empty pop-up window with message
{"success":false,"message":"\u0414\u043e\u0441\u0442\u0443\u043f \u0437\u0430\u043f\u0440\u0435\u0449\u0451\u043d.","total":0,"data":[],"object":{"code":401}}
as i understand, this output is generated by assets/components/migx/connector.php file
Earlier there was button "upload" and thumbnails of uploaded files in this window
As i see, this window is opening in frame, all other windows are just html code and working fine
I stuck about 2 days and now i ask for a help
