I'm glad to see I'm not the only person having issues with the latest update and resellers not able to create new lines or renew current lines.
I've updated from mods13 to mods14 this morning and now its become a nightmare. All my bouquets are assigned in the groups (like they always have been) and when a new account is created it crashes the page when I click purchase. It wont let me renew a current line either, same issue. I have tried enabling and disabling the 'Reseller customize Bouquet' setting but it doesn't help. I still I don't see any bouquets showing in the purchase/renew page, I've remade my main server and that didn't work either.
I've checked my Database and the bouquets are fine, I as admin can create/renew lines but resellers can't do anything.
UPDATE: Ok, so I looked at the failure and found that its the file user_reseller.php, if I restore the file from the original source package of XCUI then it works again and displays the bouquets on that package. I'm going to check the code of both, see where the error is then will post back again.
