How to disable deprecated notices in Joomla API logging

I’m working with Joomla 2.5 and my log files are getting huge because of all the deprecated function warnings. Every time I run my code, I see messages like JError::raiseWarning() is deprecated filling up the logs.

My application works fine but these constant deprecation messages are making it hard to track my actual custom errors and exceptions. The log files grow so large that it becomes difficult to find the important stuff.

Is there a way to turn off these deprecated warnings while still keeping my own custom error logging active? I want to see my application errors but not all these framework deprecation notices.

I had good luck editing libraries/joomla/error/error.php directly on old Joomla 2.5 sites. Just comment out or tweak the deprecated warning functions that are spamming your logs. You get way more control than changing error reporting settings across the board. Really helpful when third-party extensions throw tons of deprecation warnings. Just document what you changed since updates will wipe it out. This way you still see real application errors but kill those annoying framework deprecation messages cluttering everything up.

You can address this issue directly from the Global Configuration. Navigate to System > Global Configuration, select the Server tab, and find the Error Reporting setting. Change it from ‘System Default’ to ‘Simple’ or ‘None’, depending on your needs. I’ve applied this solution on older Joomla sites dealing with similar log clutter. Choosing ‘Simple’ allows you to see fatal errors and warnings while eliminating deprecated notices. However, avoid ‘None’ in production environments, as it may obscure critical warnings. Stick to ‘Simple’ to capture genuine issues without excess noise.

hey, just modify your configuration.php and set error_reporting to E_ALL & ~E_DEPRECATED. that way, you can avoid those pesky deprecated warnings without missing your custom errors. it really worked for me on 2.5!
