Indexhibit Support

Hello, guys. I making the first website on Indexhibit for social project. I made a draft version on eightwetlands.by/sea/">eightwetlands.by/sea/, just a subdirectory of another website on my GoDaddy hosting. And everything was fine. Now I need to change the domain to ecoschool.by, real work name and not just a subdirectory.
I've connected the new domain to GoDaddy's hosting and set the root path to where it already been and worked well "/sea" and than all internal pages on my indexhibit website don't work, but admin panel ok and preview of every internal pages from the admin panel works fine, but outside of admin it's :

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

Apache Server at ecoschool.by Port 80

I'll be very grateful if you could help anything.
Thank you

Maybe a host/server configuration issue? Did you ask your host if mod_rewrite is enabled in your server?

But I didn't change the hosting, I've just added a new domain name to already existing subdirectory on my hosting where Indexhibit was configured and worked fine. Hosting hasn't been changed. Is it possible that something could change on hosting?

maybe it's the combination of the two - new domain and subdirectory that somehow breaks things. Maybe it's an htaccess issue.
That's why I would ask my hosts opinion on this.

mod_rewrite is enabled on godaddy (mod_rewrite on godaddy)

so, it's hardly host question, right?

It is a hosting question. You need to set the paths in the htaccess file - threre are threads around here with info about that.
