Upgrading - UPS module not allowing checkout

[mgrostick]

Checkout wouldn't proceed and recieved blank page or server cannot be found after upgrading. Flat rate and the UPS module for shipping. Turned off UPS module and checkout worked fine. Turned UPS back on checkout no go. Uninstalled and reinstalled UPS - same problem. Really would like UPS mod to work. Any help would be greatly appreciated.

1. what version are you upgrading "from"?
2. what other mods/addons do you have installed?
3. what version of PHP?
4. what version of MySQL?
5. what are your server's errorlogs saying when this happens?
6. would you upload the zc_install/techsupp.php to your server and post a URL to it? (I'd like to check on things like cURL being installed, PHP functions being restricted, etc)

1. I believe it was 1.2.7
2. I dont think im using any other custom mods
3. php 4.4.2
4. mysql 4.1.19

Just a heads up ... your continue shopping button has a typo ...

OK thanks.

I don't see anything immediately obvious. But your site does run quite slowly.

I suspect the problem with your UPS module may be related to some edits you've made to customize the language in the module? includes/languages/english/modules/ups.php ?

[mgrostick]

I haven't modified that file.

I looked at ups.php file and it had a space at the end but still didnt solve the problem.

If I were to look at your site, the procedure I would follow to find out what's wrong, in addition to the questions asked above, would be:

1. download all your site's files by FTP to a new temporary folder on my PC
2. run WinMerge to compare all your site's files against a freshly-unzipped copy of the same version of Zen Cart
3. identify all the differences, and check each one to see if it could cause the problem
things I'd be looking for are:
- unexpected blank lines or spaces at top or bottom of files
- customized code that's missing closing brackets ) or braces } or semicolons ; or quote marks ' and "
- incomplete files that may have not been uploaded properly
- mods that have been installed, and whether they've been done right or not

In most cases it's a result of define() statements being customized and missing the closing ' or ') or '); or maybe using ' marks inside strings but not using \' instead so the ' is treated properly.
Second most popular is poorly-written mods.

The other possibility is that your server won't talk to the UPS server properly using the PHP "fsockopen()" function...which would be a result of your host's PHP configuration settings being set to block this function from talking to external sites.

OK thanks. I'll try the file compare and hopefully root out the problem that way.
