    • mysql\/error.log<\/code> \u2192 Database issues<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Restart Services<\/strong> sudo \/edx\/bin\/supervisorctl restart all<\/code><\/li>\n\n\n\n
    • Clear Caches<\/strong> sudo \/edx\/bin\/supervisorctl stop all sudo rm -rf \/edx\/var\/cache\/* sudo \/edx\/bin\/supervisorctl start all<\/code><\/li>\n\n\n\n
    • Check Disk Space<\/strong>df -h<\/code>\n
        \n
      • If storage is full, delete logs: sudo rm -rf \/edx\/var\/log\/*\/*.log<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
