 * I cannot figure out why i get the 404 when i activate the plugin. it says its
   missing plugins.php but it is on the web server. I have tried deleting and re-
   adding via ftp several times. I didnt have this problem when i activated it on
   my test site but on our production one it continues to give me a 404 with this
   in the url bar:
 * [http://mysite.com/wp-admin/plugins.php?action=activate&plugin=slideshow-jquery-image-gallery%2Fslideshow.php&plugin_status=all&paged=1&s&_wpnonce=6fb72da0ff](http://mysite.com/wp-admin/plugins.php?action=activate&plugin=slideshow-jquery-image-gallery%2Fslideshow.php&plugin_status=all&paged=1&s&_wpnonce=6fb72da0ff)
 * I also tried to re save the permalink settings which was suggested in another
   forum with no luck. Plz help!

 * It could be that the slideshow is activating so slowly that there’s server timeout.
   In this case it would probably help to disable the slideshow installation process.
   This runs at activation to make sure everyone’s slideshows are preserved when
   updating.
 * You can disable this process by going to the ‘`wp-content/plugins/slideshow-jquery-
   image-gallery/classes/`‘ folder and opening the ‘`SlideshowPluginInstaller.php`‘
   file with a text editor. Then look for line 29 and 30. These lines look like 
   this:
 *     ```
       if($currentVersion == null || self::firstVersionGreaterThanSecond(SlideshowPluginMain::$version, $currentVersion))
       	self::update($currentVersion);
       ```
   
 * Delete only those two lines, then save the file. After that, please try to activate
   the plugin again. Hopefully, it will activate successfully then.
