I'm sorry, but I have to say it

No, to be honest I experienced them a week ago. The database refused to connect (I couldn’t inizialize mysqli).

So I guess this problem is solved. Thank you.

The main problem is that I can’t change some flag, and a list of disabled flags (such as auto_prepend_file or upload_max_filesize) would be really useful.

But in some cases, even if I do not change anything related with them, flags like output_buffering (see this post too, it’s mine) get disabled on their own.

The same problem you described in this post (“Could not read line from socket” or a non-working login message), so I just have to wait you fix this bug.

If it can help, when the FTP works but is slow, the files are updated immediately after I start uploading them (I checked it inside the file manager), but the FTP client stays on that file for a lot of time: so it seems a problem related to the “server response” (I don’t really know how it works) more than to the uploading process itself. Hope it helps, good luck!
