hi,
yeah, we got really bad problem with slave server, momentarily is down, and it seems site is working better without it. I think, there is some problem with networking stuff, so it behave really strange, and it was really hard to find out this issue. On other side, we want add more servers for API stuff, because technically, now www and api are really separated (runs on different boxes), so www should work faster, and API slower, but this should be changed in future. There are a lot nice uploads using API.
For logging-in malfunction - while tuning the performance I forget put some check in LogIn() function, so it throws back "false", but now it is fixed. Sorry for any inconvenience caused.
I am still on holiday (and I will be till 26th august), but I got mobile internet, so I can check whats going on, and bed, I am working even here
