Configurable Options Problem

[Mohamed Yousry]

Why i see White Page not loading when i add Configurable Options then Click update Package Option
not load any thing .. Although i have update to 4.8.0

I see this message 

This site can’t be reachedThe webpage at https://mydomainname.com/admin/package_options/edit/21/

might be temporarily down or it may have moved permanently to a new web address.
ERR_CONNECTION_ABORTED

Although all files working fine but i don't know from where this?

Something like that is usually caused by the server actually being down temporarily, or perhaps a client-side computer/browser issue. Try using a different web browser and see if you continue to get the same error. You should also try from a separate computer.

You can also check your Blesta error logs to see if anything more specific caused an error at the time you got the error in your browser. If there is an error, it would be useful to know what it is in order to debug the problem.
