Multisite or WPML for Multi-Languages Website

Well this is dependent upon the requirements .IF you want totally isolated courses in terms of language (i.e. for example you want that arabic users should do only arabic courses ) then you can use the multisite installation would be ideal . If you want user can do course in many different languages then in this case wpml would be ideal . However wplms is a buddypress based theme and wpml is not 100 % compatible with the buddypress in terms of directory pages and profile pages but manu of our users still using wpml plugin and choose it over multisite installation coz it will be easy to manage one rather than managing multiple sites .  

Hi there, Last time I checked your site I created a course which was perfectly working in all the three languages you're displaying in your site. Please clarify the issue. Please go through the previous topics and you'll find the answer.

No this cannot be problem with the Buddydrive .The product meta problem is due to your wpml meta settings . Please do not let wpml copy the meta of the product with ,It will create conflicts .Try creating a new product and try replicating the issue with courses saving after you disable copying of meta with wpml . Please refer this tip for buddydrive fix : https://wplms.io/support/knowledge-base/buddydrive-2-0-0-fix/

We checked your issue and was not able to detect the reason behind the issue , So we tried to add the wplms woocommerce plugin in your site which changes the meta data saving a bit and it fixed the issue with the course saving . Please check and confirm .
