Hello Everyone

I have a question concerning general work process and folder structure with concrete5.
I'm not a professional and the site is for a non-profit organisation with volontary work.

We have version 8.3.2. running.

My idea is to have multiple subfolder like this:
root/concrete5_v1
root/concrete5_v2

So v1 would be the running live version of the website. V2 would be the developing version. Where I update concrete5 to the newest version and to check compability with themes and plugins.

So I want to achieve that when a user is typing mysite.com, he will be directed to root/concrete5_v1. But it seems concrete5 dont like it much. I started the insallation in a subfolder because the old site is running in the root folder. (pure custom php)

In Plesk in the admin panel from my hoster I can define the root folder as:
httpocs/concrete5_v1 or to the version I like.
But in this case I can't access the other installations. And for now, I also have some issues, that the homepage doesnt work anymore. (In the logs it seems that a loop is creted somewhere and then my IP is blocked from the hoster because of DDOS Security.)

Or is it better to do it completly with the rewriteEngine in .htacces in the root folder?
And not to make it in plesk?
I tried to mess around with that, but I didnt found a solution that worked.

Any good advice or tips how I can achieve a good working solution?

Thx for any help.

Daniel
