 * I’m getting “Error!” when trying to install the **Regenerate Thumbnails**,
    **
   Reveal IDs**, and **Theme Test Drive**.
 * It’s not clear what’s the reason for this error. I’d appreciate some assistance.
   Otherwise, is it possible to contribute to this plugin?

 * The error messages could definitely be better. Does it only happen on those three
   plugins?
 * If you’re interested in contributing, we’re working on Github: [http://github.com/automattic/developer](http://github.com/automattic/developer)

 * activating Developer, then Reveal IDs gives following message
 * `<br /><b>Fatal error</b>: Call to undefined function get_error_message() in 
   <b>/home/xxxxxxx/public_html/wp-content/plugins/developer/developer.php</b> on
   line <b>347</b><br />`

 * Thanks for the heads up, summit. I’ve [pushed a fix](https://github.com/Automattic/developer/commit/c4e01c31ac288dabd721b04fa47d67beae4c6278)
   so you should no longer get fatal errors.

 * I’ve just installed the plugin and i cannot install none of the plugins.
 * I check that fix mentioned above is in the source code.
 * Any suggestion?
 * Thanks in advance;

 * Getting an error installing other plugins aswell:
 * `Fatal error: Call to a member function get_error_message() on a non-object in/
   var/www/vhosts/denelan.com/subdomains/logic-engine/httpdocs/wp-content/plugins/
   developer/developer.php on line 397`

 * For what it is worth, I had the same problem when trying to install these plugins
   from the Developer plugin page under tools on a multisite install under conditions
   where I couldn’t install any plugins from the webUI because the appropriate directories
   weren’t writable by the userID the webserver was running under.
 * Once I’d changed the directory permissions to the point where I could install
   plugins, this error in the Developer plugin went away.
