IPN Failure

[marita]

When a client pays me, the system goes as Failed and not renew my membership site that uses joomla AEC system. Paypal send to me that:

Everything worked fine before, I did not change. The problem is that not what is the IPN address, I do not know much about it but honestly I need your help to solve this because I'm losing a lot of money. I appreciate your prompt response!

Paypal send to me this but im not sure where i find the correct IPN! Please help!

Paypal email:

f you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information.

Once you or your service provider fix this problem, you or your service provider can resend the failed messages from the IPN History page. If this problem continues, PayPal may disable the IPN feature for your account.

Thank you for your prompt attention to this issue.

Thanks,

PayPal

I have Apache running in freebsd 7.4 the web site is under construction and I have installed the perl code from the paypal site and used the instructions from paypal everything is setup but I dont think that paypal is connecting to the file on the server /usr/local/www/apache22/cgi-bin/paypal.pl

i have checked my server logs and this is what im getting

I have also changed the permissions of the files cgi-bin to 755 and paypal.pl to 755

but when a person pays the subcription they get a new user name and password but it dont put the data  in my .htpassword file 

I think that the whole proble is that paypal cannot access the paypal.pl file

here is the address that i put in the paypals site in the ipn area  http://yearb.com/cgi-bin/paypal.pl

whats next?
