   Recently installed this plug-in and tried to activate it. When I did, I received this error message:

   The plugin does not have a valid header.

   And it refused to install.

   Any thoughts?

   A follow-up:

   Tried to activate it a second time and it did NOT return that error message. HOWEVER, the configuration section is filled with HTML code. For example,

   Manage Slides ( Html -> link(__('add new'), $this -> url . '&method=save'); ?>)

   Something funky is going on.

   You don't seem to have PHP short_open_tag support enabled on your server. In order to use the WordPress Slideshow Gallery plugin, you'll need to turn on PHP short_open_tag in your PHP configuration. You can ask your hosting provider to do this for you.

   All the best,

   hi, contrid

   i'm developing locally, using mamp 1.7.2. do you know how to enable short_open_tag support using mamp? thanks.

   additional note: i uploaded the plugin using the "add new [plugin]" feature in wp. that's when i got the message regarding the header.

   next, i tried activating the plugin from the "manage plugins" feature in wp. when i did that, i received this error message: Uploads folder named "slideshow-gallery" cannot be created inside "wp-content/uploads"

   Hello everyone!
   I also experienced the same problems as described above. I was using the web based installer through WordPress and I kept receiving the Invalid Header Error when I tried to activate it.

   My Fix:
   So I FTP'd into the plugins directory and then manually deleted it.
   Once deleted, I manually uploaded the slideshow-gallery folder to the /wp-content/plugins/ directory.
   Once uploaded the directory structure should look like this /wp-content/plugins/slideshow-gallery/
   After everything was uploaded I went back in and activated the plugin without any errors.

   I next encountered the Uploads folder named "slideshow-gallery" cannot be created inside "wp-content/uploads" Error.

   My Fix:
   Create a new dirctory/folder under /wp-content/uploads/ named slideshow-gallery.
   The directory structure should look like this: /wp-content/uploads/slideshow-gallery/

   Once that was completed everything worked great... Hope this helps.

   Granted it would be nice if future releases would utilize the built in media management features built into WordPress. All in all I really like this plugin. Great work!

   The latest build (v1.0.3) which was just released doesn't utilize the PHP short open tags anymore so it won't give those invalid header errors and it also makes use of the built in media uploader of WordPress. You can easily display the gallery images of any post/page with a "post_id" parameter in the [slideshow] shortcode like [slideshow post_id=7].

   All the best,
   Antonie

   Thanks John,
   Your expertise really helped me and I was able to apply it to setting up a "buy me a coffee" plug in on my blog - and telling the story.
   Where would we be without Google search and the people who post questions and answers.
