OK --- Figured out what was going on with the DB failure. 

Please upgrade your product --- new version 2.30

Check access rights and is still set for 755.

Will try another payment.

Tested again and still no show on main page or IPN's.

I seen the other post and upgraded to 2.29.

At Paypal:
PayPal's Instant Payment Notification (IPN) allows you to integrate PayPal payments with your website back-end operations.
      
Instant Payment Notification (IPN)         On
Instant Payment Notification (IPN) URL:         http://syopscp.com/components/com_mh2treasury/ipn/ipnppd.php


Now when I test after upgrading to .29 I get:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@syopscp.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I will go back and check the rights again.

Please provide me with the URL

Sorry -- my bad.  I forgot to add the configuration to the module as well.

Another update will be out in a few minutes.

What is your URL?

Tested still no luck....

After above test of IPN link, even when errors listed.  After test went back and check DB... see below.

Database exist!    
    Tables exist!

I check the Rights for the IPN directory and it was set to 755 except for the ipnppd.php which is now 755.  Ran test link and now I receive this:

Debug mode activated

mh2Treasury Component

PayPal Instant Payment Notification script

See below for status:
----------------------------------------------------------------
Connection to db - **FAILED**
Assigning Post Variables
Opening connection and validating request with PayPal...
Connected to PayPal
Selecting database...FAILED - err:
Executing test query...FAILED
PayPal Receiver Email: MyEmail
----------------------------------------------------------------
If you don't see any error messages, you should be good to go!

Testing again now to see if all works, will repost.

Yes I was using 2.28 but upgraded to 2.29 and I am still having the same issue.  Thanks for checking into it.
 

Hello,

I installed awhile ago and have been trying to get it to work with no luck.  See: syopscp.com

I have paypal setup, IPN set, made 3 donations, all came through but does not show on main page.  The one entry on main page was manually added.

I know it's something silly it always is... but any help would be great.

Joomla - 1.5
Paypal - Setup

Hosting at: SiteGround
DB used, main site

Thank you,
SAPPER
