Yes !!! got it…
Ok … this is what I did:
1- Enabling the “php_curl” in WAMP resolve the message : “There are no HTTP transports available which can complete the requested request.”
2- “reset” the information (various times) on the “dev.twitter.com” the problem with the “You need to authorize Twitter Accounts” disappear (the blue button will work). Remember to update information and press the “Activate Account” on each attempt to “reset”.
3- At this point the account was succesfully activated (yayyyy !!) but widget didn’t show on left footer ??
4- I then go to “widgets” in the wordpress admin area and found that the previous “widgets” shown up instead of the Twitter (don’t know why). I then proceed and remove all “inactive” widgets and voilá !!! the Twitter Widget Pro appears on the left footer.
?? hope this info helps someone.
