Are there any *.json files in the folder? If not, that means P3 can't (or isn't) creating the profiles during scanning.
no json-files are created. folder is 777 and "working"
To determine if P3 should be creating these files, but isn't, use "Advanced settings -> Debug mode."
debug is empty/not created
("Profiling Enabled","Recording IP","Scan Name","Recording","Disable Optimizers","URL","Visitor IP","Time","PID") - thats all
To determine if P3 can't create these files, try chmodding the profiles folder to 777 and running another scan.
done, no success.
i played a little - creating files works. i think the problem is somewhere about ajax_start_scan(). i added a random file creation here and it isn't executed. the auto walk through pages with the iframe seem to work.
