Doesn't recognize my IP

Are you behind a proxy server or any firewalls?

Hello Pippin, thank you for your quick answer; but unfortunately, no, I am not behind such stuff.

Edit: oupss… typos.

Could you tell me the other plugins you have active?

Hello,

I use the followings plugins:
Breadcrumb NavXT
CGC Maintenance Mode
Contact Form 7
Revolution Slider
Twitter Widget Pro
WordPress SEO

It also ran “Lite Cache“, but I disable it, thinking it was the responsible (which is not).

Thank you for time.

Hmm, none of those should be causing issues.

As a quick test, does it work with one of the default themes, such as Twenty Twelve?

No, it was running with Soufflé. As I was encountering problem, I finally opted for an uninstall of everything (WP) and relocated it in another folder. Thanks for your help.

Ok!
