* I get this error meassage when activating:
* Warning: call_user_func_array() [function.call-user-func-array]: First argument
is expected to be a valid callback, ‘register_mysettings’ was given in /xxx/wp-
includes/plugin.php on line 395
* It activates, but this error shows all over the dashboard.
* The View All Team Members has a rogue bit of php code – ?> after it. This may
be part of the issue, a typo rather than a genuine bug.

* Hello Nathan,
* I have updated the code and corrected both of these. Thanks for reporting the
error. Please change the “broken” to “working” if your error have been corrected.

* Hi there,
* Thanks for the swift response.
* I deleted the old plugin and downloaded again from the plugin directory (1.0)
* I got this error on activation:
* The plugin generated 17 characters of unexpected output during activation. If
you notice “headers already sent” messages, problems with syndication feeds or
other issues, try deactivating or removing this plugin.
* However, the header error noted previously is now gone.
* It is conflicting with Super Cache in some way it seems, but even when I deactivate
that plugin, it is not saving new team members.
* The live site shows this error message at the top of the page with Super Cache
activated:
* Warning: Cannot modify header information – headers already sent by (output started
at /xxxl/wp-content/plugins/flipping-team/flipping_team.php:109) in /xxx/wp-content/
plugins/wp-super-cache/wp-cache-phase2.php on line 77

* Hello,
* Sorry for the error faced. There was a hardlink that I have corrected. The plugin
should work now. Sorry again for the inconvenience.

* It is nearly there… the error messages are all gone now!
* I am using the 1.2 version. There are a couple of minor things still! :-0
* The plugin is not calling the complete path to some resources:
* wp-content/plugins/flipping_team/jquery.flip.min.js
* rather than:
* [http://mysite.com/wp-content/plugins/flipping_team/jquery.flip.min.js](http://mysite.com/wp-content/plugins/flipping_team/jquery.flip.min.js)
* I think there is a a bit if WP php code that you put in to give the full path.
* Also, the style sheets and JS files are loading into the and not into
the header.
* Last thing for me is a theme issue. Your team.php calls the sidebar, but some
themes do not call it from the page template. I removed it by hand and the layout
came back the way it should have been 🙂 Just thought you’d like to know!

* Your page template calls the JS and stylesheets, but does not (and I think cannot)
place them in the header.
* I checked the WP Codex, and the best way to do this would be from the admin (
flipping_team.php), with a call like:
* ’ ); } add_action(‘wp_head’, ‘writeCSS’);

* Hello Nathan,
* Sorry for the delay. Was attending my classes. I have update the code with the
following changes :-
* Corrected all the links ( the confusion was because I was assuming a directory
flipping_team though I got flipping-team)
* Added an option to add/remove the sidebar to suit the theme.

* OK… nearly there…
* The styles and js are loading in BEFORE the doctype and the flip.min.js still
needs and absolute path to the file. This is what my header looks like from the
very top:
*
*
*
* tag – as the above code shows.
* These lines in team.php is missing the absolute path call:
* `12: `
* and
`18: `
* I know that when you call a theme style you use:
* `src'"/my.css"`
* I’ve been looking at the Codex for the plugin URL call of this. I’m a bit new
to making plugins, so I don’t yet know what the code equivalent is.

* How does it matter If the call is not absolute and relative?

* Because you can’t call this file from the page header:
* wp-content/plugins/myplugin/myfile.css
* it has to be:
* [http://mysite.com/wp-content/plugins/myplugin/myfile.css](http://mysite.com/wp-content/plugins/myplugin/myfile.css)
* Hence the use of , or something like to call that part of the path and create the full path in the page header.
* So, as an example, if I was calling a file that was in my theme folder, I can
write it like this:
* ``
* This will output the link in the page header as:
* [http://mysite.com/wp-content/mytheme/sponsor.css](http://mysite.com/wp-content/mytheme/sponsor.css)
* I just don’t know (yet) the echo for a plugin path…

the error. Basically I simply added

* Hi there, yes, I hadn’t thought of that echo code.
* The css and js still loads onto the top of the html before the doctype. All the
other plugins load their link files after the main theme css in the
