I can not access my admin panel
 

Hello, I performed the update 4.0.7 to 4.1.3, they were fine but when come back to the admin of the forum, I enter the identifiers in a vacuum, let me explain: after calling the admin panel, I have a first security is going well but then, once the frame to fit conventional username and password, I returned, he said "thank you for being connected" and I back on this framework to enter my username and my password indefinitely. I tried it under Chrome, Firefox and Internet Explorer.

My forum is here

Any idea?
How can I access the admin?
Thank you for your help

Make sure you uploaded all the new files to your admincp. If you had renamed the admincp, make sure you uploaded the admincp files into your renamed directory.

it seems to be all present and I have not renamed the admin.

thank you for your help, someone helped me and it was from a security module (replacing the admin panel) that had not been updated ;)
