I am experiencing a critical UI layout issue with my Discourse instance after updating to the latest version today.
When the user interface language is set to Persian (RTL), the entire layout appears broken and scrambled. Various UI components are overlapping, misaligned, and generally rendered incorrectly. I have attached a screenshot to illustrate the problem clearly.
However, when I switch the user interface language to English, the layout renders perfectly with no issues whatsoever. This strongly suggests the problem is specific to the Persian language localization or its interaction with the updated Discourse core.
I have already attempted basic troubleshooting steps such as clearing browser cache and testing on different browsers, but the issue persists consistently when Persian is selected.
Could you please investigate this matter?
Thank you.
To provide further clarity on the issue, I have annotated the attached screenshot. You can observe these issues firsthand at mobahasah.ir.
As illustrated, when the interface language is set to Persian (RTL), the DiscoTOC generated table of contents displays incorrectly, simultaneously showing both the table of contents and the timeline. Additionally, the Google Font component is non-functional.
Furthermore, applying different themes does not fully render; for instance, the main forum background color remains unchanged. All these issues are resolved by switching the user interface language to English.
