Q. After install visual composer my visual composer editors comes only in content any where but not show in CMS page.
This is happen you have disable the module and controller overwrite system from
Performance->Debug section. It's correct settings is like bellow.
After disable that. Save and you will see your editor comes like bellow in cms page.
Some time the above solution may not work for you. If you overwrite folder have write permission problem then overwrite template will not move in that folder.
Check bellow location your template exits or not.
If the file do not exits the move that from
to the override folder
If the above solution do not resolve your issue, please check your visual composer is hooked in displayBackofficeFooter
Then your issue will resolved. Now you will see the editor button in your cms page.
