I have Magento 2.1.4 and recently attempted to upgrade an extension but afterwards whenever I deploy the static content, it loses the CSS/JS on the front and backends.
php bin/magento setup:static-content:deploy
I have noticed that the path to my CSS is for example (I have turned the versioning folder thing off)...
However when I look for the folder above, en_BG does not exist. It is 'en_US' instead.
The same sort of behaviour is the same for the backend. The path to the CSS says...
But when I look for that file, 'en_US' does not exist. 'en_GB' exists instead.
If I just rename the folders and make sure they exist it works fine, but my question is why would this be happenning?
The site is setup to be en_GB (United Kingdom)
