After install the patch SUPEE-6788 when I install new module after clean cache, logout and login, I have tried to access to module configuration in admin panel and it shows Error 404.
How can I solve it? It happens with all modules that I have installed.
If the module you are installing has not been upgraded to work with the new Admin Route path restriction contained in SUPEE-6788, you will need to contact the developer that produced the module and get a new updated version that is compatible with SUPEE-6788.
Thank you for your answer. The modules I have installed are compatible with SUPEE-6788, so I don't why it doesn't work.
