Hi,
Please try following suggestion first:
Flush your browser cache any caching plugins you are using. Here is a excellent guide on how you can empty All Caches using your cache plugin settings area.

If this does not work for you, try following suggestions:
1) Deactivate all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
2) Switch to the default theme to rule out any theme-related problems
3) Reset the plugins folder by FTP or phpMyAdmin because sometimes, an apparently inactive plugin can still cause problems.
Thanks,
