Yes, I have faced same issue several times.

Have you tried changing the log level?

Have you using auto hide logs option?

I have observed that if the logs are big enough it takes some time to open, may be because of the size of the log.

I am executing small piece of code.


string s2 ='This is Bob\'s string';



and log levels are like below


General trace setting for user
DB :info
Apex code:debug
Validation :Info
Profiling :info



Can you please tell me what is the difference between info,Error,warn,Debug,fine,finest,Finer.


Thanks  in Advance

I don't exactly know why this happens, but I have observed that when you leave your dev console inactive for a long time, it stops opening logs. Just close the dev console and re-open it again and it will work fine.

Hi V'Nath,

It could be browser issue. Try to check your code in google chrome.
I was told my log would not load in the developer console since it had reached the maximum size of 2 mb.  The same log is vieable via the logs page in SF, but it cuts off at the 2mb point.  Why the developer console is not able to display in the same manner is a bug to me, but I was assured the intended functionality was for it... to not work...

I ran into this issue and tried everything: clearing browser cache, switching to a new browser, deleting old logs, etc.  I was finally able to get the Developer Console to start opening logs again by adding myself as a monitored user under Setup > Logs > Debug Logs > Monitored User > New.

This requirement seems to be new behavior.  My dev org just upgraded to Summer '15, but I can't say with certainty that's related. 

This was a giant pain in the neck.  So much so that I'm switching to the IDE  (which was running system.debug statements just fine during this issue).

I hope this helps.
