I am trying to set up the checkout payment system on OJS 3 with Paypal.
Unfortunately the checkout doesn’t seem working properly. When I click on the “price button” in the article page the page keep calling itself creating a endless loop.
This happens anytime I am logged as normal user. If I am logged as administrator the “price button” leads to the PDF article page as usual (skipping the checkout process).
A transaction error occurred. Please contact the journal manager for details.
Can you check your PHP error log for something relevant? There should be something there. (I just performed this now, so that should give you an indication of what time to look for in your log files. Note that logs are not always recorded in the same time zone as you are using.)
