Of course, you could have just done [a search](http://search.wordpress.org/Cannot+modify+header+information) and found this out yourself. * [laurieann](https://wordpress.org/support/users/laurieann/) * (@laurieann) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228118) * Omg! How rude of that person! In reference to You Could Have Just Done A search And Found Out Your Self! This person would have not asked for help if they knew this and that is what this Support Forum is for. Get some people skills. * [Beel](https://wordpress.org/support/users/beel/) * (@beel) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228119) * laurieann, you have read too much into the post and, as a result, were rude in your accusatory response. The answer was provided and perhaps, if your interpretation is correct, future redundant questions avoided because now “they know this.” * ifelse has helped many people over the past year, and hasn’t posted just one question and a personal attack. * If you choose, stick around and be helpful to others also. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228120) * And, just so you know what fueled ifelse’s frustration, a search for “Cannot modify header information” currently returns 1,221 results. 90% of those results are individual forum threads. And, most of those threads were created without searching beforehand. * [Beel](https://wordpress.org/support/users/beel/) * (@beel) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228121) * And those of us who assume ifelse was frustrated read our own feelings into the post which, of course, isn’t necessarily so. If read without our own baggage, one cannot make that assumption based upon what was written. * Just something of which to be aware when reading the posts of others: what was actually written vs. what we read into it. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228122) * > And those of us who assume ifelse was frustrated read our own feelings into > the post which, of course, isn’t necessarily so. * You are very correct about that. I’m sorry, I must apologize for my previous post. The new “Cannot modify header information” threads always frustrate me ( probably because search for those words returns 1,221 [mostly] helpful results), which is why I automatically assumed that ifelse was frustrated. But, if memory serves me correctly, ifelse has never been frustrated on these forums. * [Beel](https://wordpress.org/support/users/beel/) * (@beel) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228123) * Feel free to read into “those of us” 😉 “Pitiful creature of darkness, what kind of life have you known? God give me courage to show you, you are not alone! ”( trivia quote) * Well, this has been fun – the original post was a month or so ago. Luckily only the two of us took the bait 😉 * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [20 years, 9 months ago](https://wordpress.org/support/topic/theme-switcher-problems/#post-228124) * Trivia Answer: * It’s a line sung by Christine from the “Angel of Music” reprise during the “Down Once More/Track Down This Murderer” segment at the end of the musical (and movie)“ Phantom of the Opera”. I’d say more, but I don’t want to spoil the plot for anyone here.
