Backend Layout Broken in Multiple HikaShop Sections

-- HikaShop version -- : 6.5.2

-- PHP version -- : 8.5.8
-- Browser(s) name and version -- : Firefox - latest

Hello,

I am experiencing a display issue affecting several areas of the HikaShop backend.

Earlier today, before noon, I updated some content and everything was working normally. Around noon, I logged out as usual. After lunch, I logged back in to continue working, but the backend display was suddenly broken.

I have not made any changes to the HikaShop code. The only thing I did was edit the content.

I have attached screenshots showing how the backend is currently displayed.

I have already tried all the troubleshooting methods I am familiar with, but none of them resolved the issue.

Thank you in advance for your support!

Kind regards,

Wilfried
