Advanced parametres -> Email showing blank page

[NBBO]

Using prestashop version 1.5.4.1.

 

After uploading a new version of the webshop, the email system stopped working. Now the Email settings page is just blank, and doesnt seem to turn any errors.

Using contact form also returns a blank page, same as BO customer service. Contact form sends a mail to BO, but an answer from BO doesn´t give out any mails. Neither does the mails provided in mailalerts get mails  when an order is placed. Seems like all out going mail is out of function

I wanted to switch from php mail function to SMTP, but without the email settings page in BO, this seems like a challenge.

 

I think this happened when importing the new danish language pack, but since the pack is 100% translated, i can´t see what the problem should be?

 

Any help is really appreciated, i see this as rather urgent since the shop is online and have been for some time. If anything, just mention how and where i can change the mail function to SMTP.

 

Thanks.
