wrong url on express checkout - SEO mod installed

Hi,

I know this has probably already been covered somewhere but ive looked for it for several days until my eyes and brain hurt and i still havent found the solution

We have zencart 1.3.7 - been using paypal ipn but wanted to use express checkout. Filled in all api credentials etc (many times now). Button appears as it should. BUT when the button is clicked during an order, the wrong url appears:
"https://sslrelay.com/hedgepig.co.uk/ipn_main_handler.php&type=ec&zenid=12345obscured12345"

the prblem is the &type - it should be ?type

If its chanc
nged manually in the browser then it goes to paypal. You then log in to paypal and first screen seems fine (gives your own details as a payer) then you click review payment and get:
Multiple Choices

The document name you requested (/ipn_main_handler.php&type=ec&zenid=8bb1402d52d125229a2c5a04c2d4235d) could not be found on this server. However, we found documents with names similar to the one you requested.

Available documents: - /ipn_main_handler.php?token=EC-6RG214053L857990A&PayerID=XWJ4EKCYYU3VS (common basename)Please consider informing the owner of the referring page about the broken link.

We have chemo ultimate urls installled beta 3 and i wondered if this was the problem BUT I get the same errors whether the seo urls are switched on or off (i really do need the seo urls by the way!)
We have hit a real wall with this and i would certainly appreciate anyone being able to shed some light on this. At the moment we are back to using paypal ipn and are going to have to stay that way unless this can be resolved - someone please help im prepared to beg!

Thanks in advance

If any of your installed mods alter or intercept the behavior of the zen_href_link() function defined in html_output.php, then you'll need to revert those back to the original code. The PayPal modules use that function to prepare the URLs used in communicating with PayPal.

Keep in mind that the mod you mentioned is Beta and has many known problems. Indeed, even the earlier version of that mod was perpetually plagued by problems with busting communication with PayPal.

Thanks for that Doc - it certainly gives us somewhere to start looking!

thanks again

Well, i finally managed to sort the problem!

I was using Chemo urls's - and getting nowhere. I changed to ultimate seo urls and hey presto there it is working beautifullly. Really dont know why the other didnt work but wasted more than enough time on it trying to get the thing working.
