## I've accidentally created an error in which I can no longer reach the Config-\>Database-\> Drivers configuration anymore. I get the following error. HTTP ERROR 500 Server Error | URI: | /web/config/database.drivers | | --- | --- | | STATUS: | 500 | | MESSAGE: | Server Error | * * * This was right after I uploaded an Oracle driver ODBC17.jar file. The logs show me the following, which I assume is the issue. "Caused by: java.lang.UnsupportedClassVersionError: oracle/jdbc/driver/OracleDriver has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0" How do I go about fixing this? ---

Go to the install directory on the gateway and find the `user-lib/jdbc/` folder, remove the Oracle driver you added, and restart the gateway. And then upgrade your gateway; if you go to Ignition 8.1.33 or later you can use the ODBC17 jar just fine.
