On my site motivational stories I'am getting this "Error establishing a database connection" error after every 5-6 min.I thing this may have to do with my up-gradation from shared to VPS servers.
So my question is,did any one of you had similar problem after change of servers??How did you troubleshoot it.
Does it had to do with high traffic or RAM usage??
Note:All domain's are giving same error.
My host did some database synchronization which ofcourse didn't worked.
I didn't had any problems with my old shared hosting.
Thanks in advance.
