Not really often using browsers to open my blockchain wallet, but it is working fine on the android application. Maybe if you have an android you can download the app and use it as a secondary way to open your blockchain.info wallet.
Thank you for the advice but ever since last time that I used it's android app, due to bugs, I refused to go back and used the app and instead only used the wallet directly from browser. The problem has been solved now (thanks to Mandrik | Blockchain.info Support).
In case someone stumbles upon the same issue, here's it's solutions:
1. Clearing all your browser data, including cache & cookies - (I didn't do it but was advised by Mandrik)
2. Try logging in via an Incognito window (Chrome) or a Private Browsing window (Firefox) - (Also advised by Mandrik and I tried incognito mode and worked for me)
3. If your accessing the wallet using a saved bookmarked page, like I used to do all the time, you have to delete that bookmarked page, close browser then open again and simply type in browser the blockchain.info website and try logging in and try again to send - (I found out this myself after doing step 2 and worked as well, so it seems that there were a slight change lately that triggered the buttons not to worked base on a bookmarked version that was from last revision of the site).
Locking the thread now.
