Hello out there
Do anyone has information about the possible incompatibility with JoomDonation IPN? Can you suggest a setting for me to get the Paypal IPN working with Joomdonation. I use an other app on my website but there is no issue on that with Paypal IPN. The JD support said that it is possibly caused by SCP.
Any advice appreciated very much.
Try disabling the plugin (there is a button to do that in main panel). If the issue dissapears then try disabling the "Determine option accurately" (Global Configuration -> Tuning tab).
If this doesn't solve the issue, and assuming that the .htaccess protection feature is enabled, rename the .htaccess file (i.e to old_htaccess) and after that rename the htaccess.txt file to .htaccess. This will set the original file that comes with Joomla. If this solve the issue then there is something preventing the IPN to work fine.
