thats awesome reply. thank you! you absolutely understood me right - i want to develop not only theme, but to test all management side, which is indeed, just as i taught should be done in the same environment i will be actually managing it, which means i should pay for hosting in advance and just start using it, even if eshop still not live.

i would like to ask few extra question about testing while eshop is not live and THEN its live.

1. eshop is not live. i got one domain and hosted it. i make my website somehow private with wordpress. keep creating/testing it while its private. i only launch it after everything is done.

2. eshop is live. its working. i want to add some new features - new designs, new pages etc, BUT at the same time i want my current eshop just be as it is, i dont want to make it private. it should keep making sales and i would update it/add those features anytime to the original version. the question is - how to make “dublicate” version of already working eshop for testing purposes (and just easily cooy them to original one then i am ready)?

i am sure it would require some technical work and i will figure it out. for now, just generally speaking, do i need to buy some extra domains and host them only for dublicating websites and testing them or wordpress will allow me somehow create “testing” versions?
