Getting a blank screen after code deployment in upgraded AEM 6.3

We just upgraded from AEM 6.1 to 6.3. I am getting a blank screen just after the code deployment in the new environment.

I am getting the below error in the error.log file-

*ERROR* [10.44.48.183 [1500665039114] GET /content/regent.html HTTP/1.1] com.day.cq.wcm.core.impl.WCMDebugFilter Unexpected error:

    Were you able to figure out the root cause of the issue?

    We had this same issue where I had my source code compiling against the 6.2 uber jar. I was able to resolve it by compiling my source code against the 6.3 uber jar in the pom.xml and rebuilding my source code.

    <dependency>

                   <groupId>com.adobe.aem</groupId>

                   <artifactId>uber-jar</artifactId>

                   <version>6.3.0</version>

                   <classifier>obfuscated-apis</classifier>

                   <scope>provided</scope>

    </dependency>

      Our pom was pointing to the correct 6.3 uber-jar and we have been using ACS Commons 3.9.0.

      The exception above started appearing randomly in our AEM 6.3 environment. Everything was working since July.

      We resorted to restoring from a previous backup after confirming the issue wasn't related to content or new code deployment.

      We still don't know what caused the issue.

      UPDATE:

      We were able to figure out the root cause. One of our developers manually made some invalid configuration changes to the "Adobe Granite HTML Library Manager".

      This prevented the service from starting which in turn caused the entire rewrite pipeline to fail.

      After deleting the OSGI XML config file from /apps/system/config, the environment was able to stabilize itself.
