XF 2.0 Error importing language or styles

[Radhi]

Hello
We have been in a while for a while to upload a theme or language file to the forum with this error

Oops! We ran into some problems.
Oops! We ran into some problems. Please try again later. More error details may be in the browser console.



And also appears even if we want to delete a forum or language from the forum .....
We no longer know the solution to this ongoing problem.
There are many users who object to this problem and do not know the solution.

We hope to solve the problem in the next version of XenForo.
