sarwara on "[Plugin: qTranslate X] Plugin not working with custom meta fields"

Hi
I am using qTranslate X with worpress 4.5.2. it is working fine. but when i am using css class for Custom meta fields (Custom post type). it is showing colored border on the left. which is good which means its working.
But problem comes when i tries to save the post. then post does not save and i am getting page unresponsive error. (post is working fine if i am not trying to translate custom meta fields).
Please help me with this issue (I am beginner in wp)
