When after logging in to a service you get to see this:

It is not working. Well, or it is, but not as it should. Besides, the error message is not the most user friendly, either. Besides, for a hacker this type of error message reveals easily the system the service is built on, which is always a security risk.

After pressing refresh, though, the page is loaded.

BTW, WordPress has a bug in their category handling -field. In case you write a comma to the field (id=”newcategory”), the word before the comma is not listed at all after pressing enter. Like this:

1. Write “Errors, fails and bugs” to the id=”newcategory” -field
2. Press enter

Expected:

1. You get to see the string Errors, fails and bugs” in category list

Actual:

1. “fails and bugs” is listed. Word “Errors” is not listed anywhere

Now, the reason for this might be that the field on the same page (id=”new-tag-post_tag” ) handles the commas to store separate tags, and that works as specified. Perhaps the category -field handling just uses the same functionality. And looks like to me that it is a copy-paste accident. Perhaps not tested, or then again maybe tested, but results are neglected due to well known reasons: it’s not important, user won’t do that etc.Well, this user did 😉

Now, where to report WordPress -bugs?
