Languages are supported from classroombookings version 2.17.0 and above. If you are running an older version, you need to upgrade.
Once you have purchased a single language pack or the all-language bundle, you will have the ability to download a zip file for each language you want to use. Each zip file contains a folder named after the language, e.g. french.
Extract the contents of the zip file to the 'local/language' directory of your classroombookings installation.
Log in to your classroombookings installation as a user with administrator access. Click 'Setup', then 'Language'. All available languages will be detected and displayed in a list.
Ticking the box next to a language will allow users to set it as their preferred language when updating their profile.
You can also specify a default system-wide language using the dropdown box which will apply to all users.
When updates are made to the published language packs on the website, you will have access to download the latest files by providing the email address used to make the initial purchase.
Once downloaded, follow the instructions above for installing it - replace each folder in 'local/language' with the contents from the zip file. The language changes will be reflected the next time a page is loaded in your classroombookings installation.
