canada.post.rest.rate.service.oscommerce.V2.3 in General Add-Ons Support Posted August 26, 2015 My guess is sellonline will come back - but it will be LOW priority for CP.... I`ve switched to this new REST module and its working very well. Upgrade is very simple.... as long as you have API user name and Password (they are different than sellonline). Yep Still not online. I activated fedex calculator in the mean time even though we ship with canada post, just so that we can get the orders pushed through online. I eventually got this reply from them admitting there might be an issue with sellonline: "We are working hard to get to the bottom of the issue. We are aware of a technical constraint when using TCP protocol - do you fall into that category? If so, we're investigating a viable workaround to save customers a few hours of recoding. Http protocol seems to be working fine." Not sure if that applies. I had to update my server to php5.4 as well as update my oscommerce site to the newest version to comply with the new php. All of that was due anyways (though I am probably switching to magento within the year),. but it would have been nice to have some warning and not just downtime with no fix.
