css in admin console lost after installation of modules

[Kami]

Hello,

I have been using CMSMS 1.5.3 with no problem. Today, I installed a number of extension modules. Since then, my admin console works

but the CSS with it is gone.

Is this problem known ?

Should I uninstall all modules and reinstall them ?

Thanks very much for your help, the sooner the better ... thank you (-:

Most times yes it is from modules that may not work with the version of cmsms you are using...
