We use a PHP script (img.php) called WordThumb (similar to TimThumb) to generate the image thumbnails. If the images appear broken, double check if the image file exists by viewing the image in a new window/tab (right-click on the image and select open image in a new tab). If the image file exists and error messages appears, most likely your server doesn’t support TimThumb. To enable it, send a request to your host provider to enable TimThumb.
If you prefer not to use the img.php script, go to Themify > Settings > Image Script and check disable img.php script. Once the image script is disabled, a dropdown will be available for you to choose which image size to use. The image sizes (Thumbnail, Medium, Large) can be set at wp-admin > Settings > Media. In other words, you can specify 250 x 250px medium size to be used in the index pages and 560 x 300px large size for single post page. More on Featured Image.
If you can’t upload images in the Themify panel, double check the ‘uploads’ folder in the theme. Make sure you have the write permission on that folder (755 or 777). To find out the folder permission: connect to your server with a FTP software, go to the theme folder, right click on the ‘uploads’ folder and view the folder info/property, make sure the permission is 755 or 777. Also, double check if your server allows HTTP upload. To check if your server allows HTTP upload, add a test post and upload a test image with the WordPress image uploader. If you get an error message when uploading images with the uploader, contact your host provider for assistance.
If you can’t upload images via the option panel, upload the images using WordPress media uploader or FTP. Then copy and paste the image URL manually in the option panel input field.
To disable comments on all posts/page: go to Themify > Settings > Default Layouts, tick the ‘Disable comments in all Posts’ and ‘Disable comments in all Pages’.
To disable comments on single post/page: when adding or editing a post/page, there should be a panel called ‘Discussion’. If the Discussion panel is not visible, scroll to the top of the page and click ‘Screen Options’, tick the ‘Discussion’ checkbox, now the Discusion panel should be visible below the content box, uncheck ‘Allow comments’ to disable comments on that post.
