 * You have to download an older version of the electrum wallet, in order to get
   a 111 characters master public key. you can use i.e. electrum wallet version 
   1.9.8 (i dont know if that can cause problems with your current electrum wallet
   file, so i would install it on another computer or in a virtual machine.). Then
   you create a new wallet for your wordpress shop and export a new 111 characters
   master key.
 * Maybe you can restore your current wallet data with your wallet seed within the
   1.9.8 .. but i dont know, i never tried that.

 * heres the workarounds u can consider:
    1. easiest way – – download old electrum
   1.9.8, install it, create new wallet. Save ur seed and save a copy of ur wallet
   named “woo198wallet” as this will be ur woo commerce wallet. – keep ur seed and
   ur wallet copy in safe place. Then uninstall 1.9.8 – download latest electrum
   version 2.4.4 and install it. – u can then simply open the woo198wallet in the
   latest electrum version. Then u use the MPK and ur all set. I think u should 
   also be able to use the seed during the 2.4.4 wallet create wizard. *** It might
   be wise to create ten wallets before uninstalling 1.9.8 and keep them for a rainy
   day. I understand its good practice with this plugin to swap in new fresh wallets
   from time to time so if u have a few queued fresh v.1.9.8 wallets that u can 
   use later, that’d save u some time when u need a fresh one.
 * 2. harder way –
    – there is a tool such as pybtctool and libbitcoin tools and
   u can generate wallets using same specs as electrum v1.9.8. You need to be versed
   in command line a bit but they give u instructions. – use their command line 
   to generate ur wallet, seed and MPK, etc. You should then be able to import these
   into electrum v2.4.4 during the wallet setup wizard.
 * I use #1 and it works reliably as far as the wallet creation per order based 
   on ur MPK goes.
 * I also understand that electrum 2.4.4 now has some merchant feature that might
   be a solution towards my biggest problem with this plugin – the blockchain explorer
   cronjob stuff. Electrum 2.4.4 i think offers a way to deal with this but haven’t
   gotten around to playing with it yet. Theres a bitcointalk forum post about it.
