Site is working. But if some one is ordering on site and checking out, after clicking "confirm order" page disappears.
When i click "Advance Parameters" > "Emails" from Back office, again page disappears. When i also click "My Preferences" on the top right section of My Back Office, change my password, After clicking "Save" page disappears.
When some one places an order, and i try to send an email from my back office, neither i nor my customer gets any email. I have checked and tested with my another email as well.
I think any thing related to Emails, is not working, and page disappears.
Please advice and HELP me out with this.
