If you are running a Drupal 7 site and your site displays warnings or notices which you are unaware how to fix then you can simply disable them by following the steps listed below after logging into your admin panel:
- Go to Configuration > Logging and Errors.
- You have three choices:
- None will disable all error reporting.
- Errors and warnings will display on the most serious problems.
- All messages will display all problems and is probably only useful for developers.
I am providing below two screenshots, one with the “Development” area and it’s options:
Please only use this option to temporary hide the notices and warnings on your site. While they do not represent a high concern by being just notices and warnings, they are actually reports of issues with the coding of your Drupal site and mainly occur with the use of third party modules. These notices and warnings would occur also whenever there is a compatibility issue with the server software or with other components and for full functionality of your site you should always ask a Drupal developer to take a look at them and correct as possible.
You should not use this option to hide actual errors because the errors mean that something is actually broken on your Drupal site and it’s functionality is limited. In such cases you should always hit up a Drupal developer or search for a solution at the Drupal Devil support database.
