    Well you should never ever enable develop mode on a production site and that too after it is live for customers. Simply now set it to production mode again. – Shireen N Mar 22 '18 at 07:03

    Run this command : php bin/magento deploy:mode:set production. Keep patience while it is running because there will be some processes taking place which will take some time to finish. Good Luck! – Shireen N Mar 22 '18 at 07:05

You can try following step may be it can help you :

  1. Remove all data inside directory :

    var/cache var/di var/generation var/view_preprocessed pub/static

  2. check if maintenannce.flag file exist in root/var/ directory delete that file as well

  3. run command bin/magento deploy:mode:set production

  4. clear cache bin/magento c:f
  5. check permission of file and folder (important to check) try to hit base url in browser.

  • You should really explain what these steps are doing. It was by running commands without knowing what they do that got the OP into his mess in the first place. – ProcessEight Jul 30 '18 at 09:03
  • Actually I am considering the person who is performing a task should have basic knowledge of magento default command . But If you need explanation you have following option just run : – Shashank Gupta Jul 30 '18 at 11:23
  • Actually I am considering the person who is performing a task should have basic knowledge of magento default command . But If you need explanation you have following option just run : bin/magento
    in root folder all command are well explained . secondly : deleting file under view processed will delete all static file magento generate for caching purpose . deploy mode command will change mode from developer to production . bin/magento c:f remove all cache files . and permission you need to check according to you configuration .     – Shashank Gupta Jul 30 '18 at 11:32
  • you can use chown and chmod command for setting owner and file permission – Shashank Gupta Jul 30 '18 at 11:34
  • Remember that developers (and not just the OP) use Stack Exchange to learn, not just find answers to one-off questions. So explaining what the commands do is essential to help developers do that. – ProcessEight Jul 30 '18 at 11:38

There are simple steps to overcome this:

  1. Empty content of root/var/cache/, /var/page_cache/, /var/log, /var/report ,/var/di , var/generation var/view_preprocessed
  2. run php bin/magento setup:upgrade
  3. run php bin/magento setup:di:compile
  4. run php bin/magento cache:clean
  5. run php bin/magento cache:flush
  6. run 4. run php bin/magento setup:static-content:deploy -f or setup:static-content:deploy
  7. clear cache again
  8. Every thing will be fine

  • There is no such command as php bin/magento flush. Also, there is no need to flush cache twice. Finally, switching to production mode will execute these steps, so you could've just said that (like the accepted answer). – ProcessEight Jul 30 '18 at 09:07
