503 error on joomla component
We own a eshop and the company that hosting the site use litespeed we have a joomla component that connects Virtumart with the bank for payments. All the procuder works fine exept the success page that the customer should see after his had fill his credit card info in the redirection page. we get the "Error 503. Service Unaivalable. The server is temporarily busy, try again later!"
The host company sais that is not anything wrong with the server. And the owner of that company sais that something wrong in our com_virtuemart forder where the success page is or the problem is on hosting server. I replaced it but nothing!
The order comes in normal in admin panel and we get the confirmation email from the bank.
We have the demo use for that payment system because the bank needs to see that the success page works fine.
Is something with the compatibility between php versions (component - server)?
thank you in advance!
