It appears that the wordpress.org website repository has been naming the zip file folder for the AWSOM Pixgallery plugin incorrectly leading to activation issues and other problems getting it to work. If you downloaded your version of the plugin from anywhere but here, please make sure that the plugin folder is called “awsompixgallery” in the wp-content/plugins folder. If it is called anything else it will most likely cause issues. To fix this deactivate the plugin, rename the folder to awsompixgallery, then reactivate it. This should correct the issue.
