wp-admin/nav-menus.php is locked, not worked well

Hello Friends I would first like to apologize for my English because I am translating through google, I want to congratulate the creators of Nirvana because the best free theme with unlike I’ve tried almost every web that I do them with Nirvana I have bought two templates for two draft customers and are very nice but do not work as well as Nirvana.

Well I want to ask for help for a small problem I have on the page: wp-admin/nav-menus.php has always worked well, but in the last update of Nirvana, or wordpress, or some plugin not where it comes from the problem, but now it is locked, it works one second and is blocked for 4 or 5 seconds and so on, is very difficult to move the menus.

I use the Max Mega Menu plugin, but if I turn the page’m still locked nav-menus.php

I talked to my hosting and they can not find the problem, I have recommended that you go to plugin plugin disconnected, but not to run.

Can you help me? My url is http://www.tiendascobocalleja.es

Thank you very much for your time.
