Anyway, I’m getting an error but not understanding where to see it. Like I said, the php log and the apache log look clean (using the cpanel tool to look at server log and viewing the php log directly). Seems I should be seeing the error referenced in this post in the php log.

Please send test if it’s different than what is in the zencart admin php “Configuration Test” portion of the taxcloud.php file.

First I would say that it may be possible that your current server may be compatible without any changes. I can send you a test file that you can place on your server which will determine if your server is set up properly.

There are other solutions but they require recompilation of Apache, which you would not be able to do either. Unfortunately this is a bug within PHP that we don’t have any control over.
