I installed a new extension on my site, but couldn't enable it.
ran command php bin/magento module:status I can see it was enabled, but it's disabled on module manager.
Thanks
Did you try this
php bin/magento module:enable Vendor_Extension
Although giving it more thought it might have disabled itself due to invalid key. Does have any kind of activation key?
If in doubt I would contact the extension developer.
bin/magento setup:upgrade
and then cleaned the cache?
