Undefined Index Notice

Patch results in the same error. Screenshot attached. Also, the website searched for is an existing website, so there should be results returned.

I just changed line 152 to this:

if (isset($variables['result']) && isset($variables['result']['regrinfo']['domain']['name'])) {

and now I am getting the following issue shown in the attachment on shared hosting environment, only after running a few URL's through. You will notice there was a URL that needed normalizing that was ran before these empty results appeared. Also, sometimes the output_text doesn't appear, and sometimes the drupal_set_message will disappear or in the function "domain_finder_normalize_domain_name" the message will appear twice when searching for multiple different URL's in a row.

Here are the missing messages

messages showing up twice when entering differently formatted URL's.

The new code results in the following error. It seems that these errors with the patched code from last time were only happening after entering "www."

If you don't enter the prefix, there are no errors so the www. is breaking it.

The new code provides a new message that there are empty results... but for most of these there should be results returned. In the attachment, www.yahoo.com was searched for and returned empty results. The problem is with the "www." prefix. The code is not stripping the prefix correctly. When that is fixed, the empty result problem will go away.

Another error with new tree and code.

I don't know what to say then. When you search without including the www. prefix, the code works fine. When you start to enter www., then it breaks down. I think your function "domain_finder_normalize_domain_name" is not correctly written.

You're right. Could it be an issue with shared hosting env?

One more screenshot for you to take a look at. Why would it return that yahoo.org is free?

Okay, I installed the module on a fresh install and just like before, it worked for awhile, with the exception of the .org domain showing as free (in the screenshot below), but now it is returning all empty results only in the shared hosting environment. I ran about 20 different URLs through in a row before the empty results began coming up for every entry. Could it be a caching issue?

Same result with the patch. There must be something with the shared hosting environment that is causing it. Like I said, it works for a few searches on a fresh install before the empty results start appearing in shared hosting, local works fine. I guess it's just not going to work for me. Thanks for trying to help.

edit: The double messages in attachment from comment #5 are not appearing any more with the changed values in the last patch.
