I'm sorry if this topic has already been adressed in another topic but I couldn't find it.
We recently moved our MantisBT from one Server to another, we wanted to change the version of MantisBT and managed to sucessfully upgrade it and integrate the database.
We managed to run Apache and PHP is working, we can acess our old entries and can use it as we want. So the migration seemed to have worked.
This is our current installation info:

Now to our problem:
The browser (doesn't matter which one) displays MantisBT wrong.
This is how it looks ATM:

We tried different kind of themes which did change the color and fonts, but we couldn't figure out how to get the menues and sitebars and stuff into the right position.
Please let me know if you need any other infos from me.
If you could share any information on how to fix it , we would be very gratefull!
Thanks in advance!
