Hi, I purchased the Payment form component and the DPS plugin a couple of days ago. The component installed fine, as did the plugin. I have created the forms I needed, and tested them with the offline payment plugin - everything worked fine. I installed the DPS plugin, put the pmf_dps_return.php file in the root directory, and published the DPS plugin. I entered pxpay user ID and pxpay key details into the plugin. These details are already being used on another site so I know they're good. However, when I fill out the form, and go to pay via DPS, the site returns to the homepage, and no transaction page turns up. The form data is posted correctly to the DB, set to unpaid. I am using the latest Joomla (3.9.10). I have tested the error on Chrome and Firefox. Please advise on how to fix the issue.
