We are seeing this options from Magento1, but we are not clear what types of cache will be flushed from the system/magento. What needs needs to cleaned or run at what time.
In magento 2 we refresh the cache and also flushed Magento cache, is that mean we have to once again deploy the static content here again.
After Cache clean we are unable to login in Magento admin, after checking the logs file found that var/cache folder don't have the proper write permissions. But before removing cache it has the right permissions.
Can anybody provide insights of handling the Magento cache especially the Magento2 part? As we are seeing the issues after flushing the cache from admin side.
