Confluence won't start - 404 error

Question

I'm trying to start up Confluence. After changing the amount of memory in the <confluence-install>/bin/setenv.sh file, Confluence only starts up with this page:

Looking at atlassian-confluence.log, I see the following lines:

I really don't know what to do here, and I'd greatly appreciate any advice you can give!

I just tried reverting setenv.sh, and the error is still there. The lines from setenv.sh are as follows:

CATALINA_OPTS="-XX:+IgnoreUnrecognizedVMOptions ${CATALINA_OPTS}" 
CATALINA_OPTS="-XX:-PrintGCDetails -XX:+PrintGCDateStamps -XX:-PrintTenuringDistribution ${CATALINA_OPTS}"
CATALINA_OPTS="-Xlog:gc+age=debug:file=$LOGBASEABS/logs/gc-`date +%F_%H-%M-%S`.log::filecount=5,filesize=2M ${CATALINA_OPTS}"
CATALINA_OPTS="-Xloggc:$LOGBASEABS/logs/gc-`date +%F_%H-%M-%S`.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=2M ${CATALINA_OPTS}"
CATALINA_OPTS="-XX:G1ReservePercent=20 ${CATALINA_OPTS}"
CATALINA_OPTS="-Djava.awt.headless=true ${CATALINA_OPTS}"
CATALINA_OPTS="-Datlassian.plugins.enable.wait=300 ${CATALINA_OPTS}"
CATALINA_OPTS="-Xms1024m -Xmx1024m -XX:+UseG1GC ${CATALINA_OPTS}"
CATALINA_OPTS="-Dsynchrony.enable.xhr.fallback=true ${CATALINA_OPTS}"
CATALINA_OPTS="-Dorg.apache.tomcat.websocket.DEFAULT_BUFFER_SIZE=32768 ${CATALINA_OPTS}"
CATALINA_OPTS="-Djava.locale.providers=JRE,SPI,CLDR ${CATALINA_OPTS}"
CATALINA_OPTS="${START_CONFLUENCE_JAVA_OPTS} ${CATALINA_OPTS}"
CATALINA_OPTS="-Dconfluence.context.path=${CONFLUENCE_CONTEXT_PATH} ${CATALINA_OPTS}"
CATALINA_OPTS="-Djdk.tls.server.protocols=TLSv1.1,TLSv1.2 -Djdk.tls.client.protocols=TLSv1.1,TLSv1.2 ${CATALINA_OPTS}"
CATALINA_OPTS="-XX:ReservedCodeCacheSize=256m -XX:+UseCodeCacheFlushing ${CATALINA_OPTS}"

Just to clarify, this is from the file that Confluence is currently using and is currently returning the error I described earlier. The lines from the file that didn't work are as follows:

CATALINA_OPTS="-XX:+IgnoreUnrecognizedVMOptions ${CATALINA_OPTS}" 
CATALINA_OPTS="-XX:-PrintGCDetails -XX:+PrintGCDateStamps -XX:-PrintTenuringDistribution ${CATALINA_OPTS}"
CATALINA_OPTS="-Xlog:gc+age=debug:file=$LOGBASEABS/logs/gc-`date +%F_%H-%M-%S`.log::filecount=5,filesize=2M ${CATALINA_OPTS}"

Hi Sam,

I would recommend reverting setenv.sh for the time being. Can you also post the lines from setenv.sh that contain CATALINA_OPTS? Cheers!
