Duplicate orders

[eyeb]

Hello,
v 1.5.4

Just upgraded from (much) older version (1.3.5~). Used PayPal Express and PayPal Direct in the past and present...but getting some duplicate orders now (and not in the past).

Duplicate orders have been coming in from two out of six orders (not counting duplicates).
Each duplicate has a unique invoice number
All orders (duplicates and non-duplicates) have used a coupon code - same code
The duplicate orders charge the full price for one of the orders and the discounted price for the next - (actually one of the two orders was a triplicate 2 full price and 1 discounted/correct price)
Highly unlikely that it is a double click issue - on of the duplicates is from a long time customer that knows not to do that - other customer not sure.

I've been comparing the six orders to see if there is a pattern - no pattern other than the duplicates have only been on PayPal Direct (on site checkout) and not PayPal Express (PayPal checkout) BUT there was a no-duplicate order also placed with PayPal Direct.

Anyway, I don't expect anyone to solve this problem here on the forum - just looking for suggestions on things to look at (like comparing the payment methods, etc. like I'm doing). I set Log Level to Debug in the PayPal Direct settings (assume this is a good idea?).

Thanks

Just some thoughts...

Yes good idea to set to debug in order to debug. :)

To confirm the upgrade process, after upgrade did you disable/remove and reenable/install the module(s)? (Noting the settings before disabling as they will be set to default values when re-enabled.)
Do you have any errors logged? (Now the logs folder instead of the cache folder if properly upgraded.)
Check out any of the links at the bottom of this page for applicability?

Hey, Thanks for the ideas.

One thing is I did a couple of test orders - one onsite, PayPal Direct and got the error message "Warning: An Error occurred, please refresh the page and try again." And then I did a checkout via PayPal - paid there and after hitting the submit button there got the same error message - I assume from returning to my site.

BUT I didn't see any errors in the log file - just an .htaccess file and an index.php file - does this mean there is no error with PayPal - but rather on our end - at our site? I'm guessing yes..but good to confirm. I did set up my log file folder 777.

Thanks.

Yes, the message received indicates a problem on the site. The logs directory may need to be 755 instead. Recommend trying that first, but also there may be a problem in the includes/configure.php file regarding the path for the logs... If you would like support troubleshooting that, post the file (press the # symbol on themessagebox menu bar then paste) without your DB credentials/details (can obscure them). If you post your admin version there should be no reference to theadmin directory if installed/upgraded properly...
