Hi, thank you for your reply.
I've cleared caches, and tried it in chrome and in firefox, but same thing happens.. also I've tried to go through the checkout process again with debug and error reporting but it didn't throw up any error messages for me when paypal redirected me back to the website (perhaps I am doing something wrong?? i'm not very experienced with using error reporting and not sure where the errors would show up) but yeah it still took me back to the same wrong page 403 error (also, the 403 error page is maybe from a different template, not the one that i am actually using - i don't know if that is relevant)
However some errors did show up when i just typed the return url straight into the browser rather than being sent there from paypal.. if that makes sense.
I'm actually finding it all a bit difficult to explain so here are some screenshots
This is where you are meant to be redirected to after successfully paying for an order through paypal:
...index.php?option=com_content&view=article&id=115&Itemid=1578
This is instead where I am being re-directed from paypal after paying for an order: (firefox & chrome)
...index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id=367&Itemid=
1560
If I type the address above (the incorrectly re-directed url to ..Itemid=
1560) straight into internet explorer without being sent there from paypal this is what i see : (error reporting and debugging on)
(which i am assuming is the default hikashop return screen, because of the option to view your order? minus the errors of course...)
and if i do the same again but in firefox or chrome (just type in that incorrectly re-directed url straight into the browser without being sent there from paypal) i get a different screen again, with less errors and no option to view order details..
It's all very confusing to me, so I'm sorry if i'm not providing the right information.
Thank you for your time!
