OJS content text/font display error

Hello all,
We are facing a strange problem of journal contents and menu display error in Chrome and Edge brower.

Describe the issue or problem

  • The menu and contents of our journal website is displayed in Nepali font by Chrome and Edge browsers; but normally in English font by Firefox browser.

  • The contents are not translated but only font is changed.

  • Even, the PKP Docs website also shows the same error of displaying text in Nepali font.

  • This issue is seen in some PCs but not in all. E.g. problem is in my laptop but not on my desktop.

Steps I took leading up to the issue

It is a random error affecting some PCs while others are not affected.

What application are you using?
OJS 3.3.0-4
OJS 3.4.0-5

Additional information
Screenshots added.

Any help and solution will be highly appreciated.

With best regards.
