In first, you must to activate 'Log level' option on the 'Debugging and Logging' section in 'Site Settings' page.
I recommend 'Log errors and warnings' choice.
Now you can activate 'Elgg Developer Tools' plugin and switch on 'Enable error log' option.
Now you'll able to see 'Error log' there.
The best way is regular checking the server logs.
