My droplet is running Ubuntu with Virtualmin installed and has 2 virtual servers. There is the main server, then a sub-server. My sub-server is where I am testing and running into problems. I am using the following wordpress plugin: http://codecanyon.net/item/justified-image-grid-premium-wordpress-gallery/2594251 which uses timthumb to generate the thumbnails. Inside the justified image grid plugin folder are the plugin files and timthumb.php and it's cache folder that has an index.html file and timthumb_cacheLastCleanTime.touch I have tried just about every combination of chmod and chown on the timthumb related files and folder. Here is the error I get in the log: [Fri Jan 17 04:51:57 2014] [error] [client 22.214.171.124] PHP Warning: touch(): Utime failed: Permission denied in /home/artimeg/domains/beta.artimeg.com/public_html/wp-content/plugins/justified-image-grid/timthumb.php on line 206, referer: http://beta.artimeg.com/2013/10/30/image-post/ http://beta.artimeg.com/2013/10/30/image-post/ is a post for testing. In the log file I get the following: GET http://beta.artimeg.com/wp-content/plugins/justified-image-grid/timthumb.ph…om/wp-content/uploads/Avenged-Sevenfold_760_20131011.jpg&h=280&q=90&f=.jpg 400 (Bad Request) The image file does exist as you can see: http://beta.artimeg.com/wp-content/uploads/Avenged-Sevenfold_760_20131011.jpg I am at a loss for ideas, so any help is much appreciated!
