Apliqo UX tm1web websheet issue


In a project we have strange issue. One user can access tm1web directly and she can not access the same tm1web websheet on Apliqo UX. She faces with a blank page in Apliqo.

Other users are fine, they have no problem. When we create a test user and give it the same security rights still we can not reproduce the problem. We tried to clear cash.

Do you have any idea, what could be the reason?
