How to remove exception error log messages from browser?

[kanchi777k3aa3]

My web browser currently displays a long error log. How do I remove this? I'm also facing a 500 error page. Is this why or did I enable something to trigger this? At first I thought it was because of app/bootstrap.php but I commented out this line. 

#ini_set('display_errors', 1);

So I don't think that is it.

Hello @kanchi777k3aa3 

The exception log comes for many reasons. please roll back your last code changes or remove the extension which you have installed last time.

Hi @kanchi777k3aa3 

Are you running Magento in developer mode? If yes you may switch to production mode and check the difference.

Hi @Mukesh Tiwari 

When I try to go into production mode, the process gets killed so I haven't been able to.

[Mukesh Tiwari]

@kanchi777k3aa3 Can you share screenshot of error which you get on switching to production mode?

[kanchi777k3aa3]

@Mukesh Tiwari 

Usually when I try to switch to production, it would make it past compilation and then gets killed. However, this time it gets killed early off.

Hi @kanchi777k3aa3 

Could you copy paste the errors from the system.log and exception.log file here? So that I can check and suggest some solution.

Thanks

Sure! @Mukesh Tiwari

Hi @kanchi777k3aa3 

Try to increase MySQL time out and disable recently installed plugin. Then check if it works for you.

Thanks
