I put this hoplink in the widgets sidebar and press save.
Then my original site redirected to other site (mistake). I need to fix it.
Now the problem is if I click on the Widgets button at the wp control panel, it will redirect to other site, it will not go to the Widgets page. So now I can’t removed the code that in the widgets sidebar that I made mistake before.
Actually the widgets sidebar was disappear when I click the “Saves Setting button”.
I can put the php code in the widgets sidebar because I used the plugin called “php code widget”.
