Well, I'm back at square one, again cannot generate new deposit address ...
Yesterday, after I had posted this video (https://www.youtube.com/watch?v=O7gXJTFnqyw), I was able to generate a new address  (I supposed FBC had fixed some issue).  I also tried to immediately generate another address afterwards, and it gave an error message that only 1 address can be generated in 24 hours.   So, I let 24 hour pass, and I tried again, and it does not work again, no error message, but no new address (as if the button click is not calling any procedure).

I try to check in the script what this button is defined to do and i see this:
<div id="new_deposit_buy_button">
<button class="new_button_style profile_page_button_style new_deposit_address_button_width" onclick="GenerateMainDepositAddress();" id="">NEW DEPOSIT ADDRESS</button>
<button id="buy_bitcoins_button" class="new_button_style buy_bitcoin_button_width orange_button" onclick="javascript:VisitLink('https://fluidmoney.xyz/?publicKey=WQ5P75kQZKNLT3FkuFQWfq:AJVkJbDRPVafwjfAZkxqRXkMRtBYq&amp;destinationCurrencyCodeLocked=BTC&amp;walletAddressLocked=1AXbfcsNicqddsBfo5REmXnAPnikDLmYox');">BUY BITCOINS</button> <p><small>* When you buy bitcoins using the button above, they will be sent directly to your FreeBitco.in wallet. Fiat to BTC conversions are handled by Unlimit &amp; TransFi, please contact them if you experience any issues.</small></p></div>

but i can't see any further info what this "GenerateMainDepositAddres()" procedure is doing.

any ideas?
