I have recently installed the Mailchimp extension for Magento 2 and now I'm getting the following error on the website:
Exception #0 (Magento\Framework\Exception\LocalizedException): Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory.
I have tried running bin/magento setup:upgrade but am then getting an error in SSH:
The XML in file "/var/www/vhosts/propmasters.net/staging.propmasters.net/vendor/magento/module-inventory-catalog/etc/communication.xml" is invalid:
