Hi folks, today we’ve upgraded PHP4 to PHP5. While testing PHP5 it seems everything works, but now, as you can see, you get blank page or strange characters sometimes. After debugging this issue, we’ve come to conclusion it is caused by bad communication with web server 2 and db server, so we redirect traffic from web2 to other servers. Anyway, we are doing our best to figure out how to solve this problem, so please stay tuned.
Temporary solution is turning off the cache, we hope DB server will not burn out 🙂
