When trying to change the administrator user's password for the first time on a fresh installation (the second time I've encountered the same error), a dialog modal opens, but the content inside the modal is a view of the site's initial page, and all other content is obscured.
I tested with Firefox 138.0.1 and Brave 1.78.97 on Linux, and both show the same problem.
In the Firefox console, it says:
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help see https://xhr.spec.whatwg.org/#sync-warning"
The Osticket version is 1.18.2.
Php 8.4
Nginx
The first time I downloaded the package from the website, and the second time I installed it with git clone as described in the readme.md file.
