Templates broken after working then not

[user25]

Templates keeping breaking stylesheets after moving mybb subfolder to main directory.  Two of the the templates worked briefly, one after following the stylesheet restore tutorial.  Imported templates I had backed up before attempting the folder move and restored, still nothing.  Help needed asap.

if you need direct help you can PM me temporary access to admin panel & the templates details
sometimes templates are not correctly stored in the database. in that case database access is required to check
