Theme Switcher header issue

#1 you are using style switcher not theme switcher and you have tried to implement it in the header by doc type. Add the code you have above to the side bar

<? php if (function_exists('wp_theme_switcher')) { ?>
<?php _e('Themes'); ?>
<?php wp_theme_switcher(); ?>

<? php } ?>

It is in the sidebar.

I didn’t think I had uploaded the style switcher but I checked and it was there and on.

So, turned it off and now I get another error. By putting in line breaks, I have narrowed it down to the <? php } ?> (spaced added on purpose). The error is a
Parse error: parse error, unexpected $ in (blah blah sidebar.php) line 87

Me again. I uploaded the original side bar, after switching to Batavia. It has less bells and whistles than my Gila theme which is full of my crap.

I didn’t change the code any that was originally in the sidebar, which has the ‘if function exists…’ part already in place.

Reloaded page. The parse error is gone but the original error is back.

It is in the sidebar and the style switcher is still off.

I guess I’ll force my few visitors to like whatever theme I’m in the mood for. heh heh

Okay, looked at the sidebar. If the <?php is the first, then it puts the themes outside the sidebar and on the screen all by themselves between the header and the body.

Error message now is directing back to theme-switcher.php lines 41 and 42. If I counted right, this is the offending section, starting with line 40:

select name=”themeswitcher” onchange=”location.href=\”.get_settings(‘siteurl’).’/index.php?wptheme=\’ + this.options[this.selectedIndex].value;”>’.”\n” ;
foreach ($theme_names as $theme_name) {

this is beyond my grasp of understanding. I am a Southern Blond Female. ??

This error message may be caused by whitespace either before the beginning of the theme-switcher.php script, or after the end of the script (eg, either before the “<?” at the beginning, or after the “?>” at the end).
Whitespace is any text that is not visible, such as blank spaces, line feeds, carriage returns, tabs, or any other non-printable character.
When you open theme-switcher.php in notepad, make sure that the cursor cannot go beyond the “?>” at the end of the script. If it can, remove any extra space.

The problem isn’t in the sidebar, it’s in index.php on line 3.

“output started at /home/.milkyheater/poffutt/paulaoffutt.com/blog/index.php:3”

I just checked the line 3 of the ‘main’ index.php (vs the index.php in Gila or any other theme) and it is the end of referrer-karma:
check_referrer(); ?>

So I took out all the r-k lines, made sure that no blank spaces were before the first <? and…

theme switcher now works.

Any ideas why?

as being the first to reply, I want one of my themes added!!!!:)

Which ones have you done?

Holyroller, add the RK line to the top of the index.php file in your WordPress directory, not the theme’s index.php

That’s where it was, macmanx.

Interesting. That’s where mine is and I have no problems. But, I also don’t have the Theme Switcher enabled. That must be the key.

Yes! I’ve just figured out my self, if you get a message like:

Warning: Cannot modify header information – headers already sent by (output started at /home/user/public_html/index.php:1) in /home/user/public_html/wordpress/wp-content/plugins/theme-switcher.php on line 37

Warning: Cannot modify header information – headers already sent by (output started at /home/user/public_html/index.php:1) in /home/user/public_html/wordpress/wp-content/plugins/theme-switcher.php on line 44

then, check to make sure there arent any blank spaces beetween your <? at the beginning and ?> at the end of your theme-switcher.php plug-in and your main index.php file! =D
