I relate to this well known Page Tab Tutorial by FB: https://developers.facebook.com/docs/appsonfacebook/pagetabs. The third step, after filling of page tab info and adjusting of the tab width is getting a prompt to select a page, to which the newly created tab will be added. But i don't get this promt, like it's written in the tutorial and seems to be the normal case for all users.

After i edit tab details and press "save changes", the page reloads with "saved"-message, like on this screenshot,

and i see no further given possibility to add created app to any of my pages. If i go into the administration area of any of my pages, in the tab "apps" is this newly created app not present, so i can't add it from there too. What i'm doing wrong? The solution must be simple - i go crazy:( I tried it with Firefox and Chrome, setted off all popup- and adblockers - nothing goes... Thanks for ideas and advice! Evgeniy
For anybody who will look for solution: to add a page tab to any page do it manually: edit a link http://www.facebook.com/dialog/pagetab?app_id=HERE-COMES-APPID-OF-YOUR-PAGE-TAB-APP&redirect_uri=http://www.facebook.com fill into the link the app id of your newly created page tab and run this link in your brwoser: you will get a site with the prompt from the first image i cited in the first post. There you will be able to select one or, with pressing SHIFT, many pages to add your app/page tab.
