When someone places an order on my magento website I do not receive emails that they have been placed, also the contact form when someone submits gives an error "Unable to submit your request. Please, try again later". I am unable to send emails to the customer through the system to update them on order status or just send general messages and lastly when you try to sign up for a newsletter subscription it says "there was a problem with your subscription". All of these items were working and just stopped and seem connected.
Thank you for your bids. MY BUDGET is $30-$50 FOR THE PROJECT.
