Hello

! Need help about this problem, I work with 1.5.15 Joomla version: my host provider had a migration of my site, changing password. I continue to update my site, but the drop-down menu doesn't work anymore, so I can't access to these options in the menu (modules, components, menus, etc.). I tried to solve this problem by copying some directories of the installation as administrator, components, inlcudes, language, libraries, modules, plugins and templates, and these files changelog.php, credits.php, license.php. Using the same process, I upgrade to the 1.5.26 without success.
Now I have to add a new menu but I can't access to the modules environment without using the drop-down menu.
I tried different browsers (Firefox, Chrome, etc.), different OS (Windows 7 and XP), different workstations: the malfunction is the same!
Can you help me, please?
