hello all i've developed a site using the Magento 2.2 platform ive created it on a local Development server running webmin and now got to the point where we are moving to it to two nginx servers one has the DB on and the other has the webfiles which in its self isnt a problem
Probelm im having is when moving the website from dev subdomain.website.com to production website.com i've made all the relivant changes in the DB and ran
php bin/magento deploy:mode:set production
The Home page comes up fine and also the CMS pages come up ok but the Catergory and product pages come up with error
Method 'getExtensionAttributes' must be overridden in the interfaces which extend 'Magento\Framework\Api\ExtensibleDataInterface'. Concrete return type must be specified. Please fix :\Magento\Catalog\Api\Data\ProductInterface
also the admin comes up with a error saying this page isnt redirecting properly
im not sure if these errors are related or not
other things ive tried are
php bin/magento cache:clean
php bin/magento cache:flush
ive also run the Re index command
and also rest the file permissions and ownership
