  PHP configuration directive "memory_limit" is not big enough

  The PHP core takes up about 5MB. You also need at least 4 bytes for each pixel in the image to resize it, regardless of the actual file size. So, if you have a 2000x2000 pixel (4 megapixel) image, you need memory_limit at least this big to be able to upload it: 5MB + ( 2000 * 2000 * 4B ) = 21MB

  If the memory_limit directive is not big enough, the upload will fail. There are many online resources describing how to increase memory_limit in PHP. Please search online for "increasing memory_limit in php" or contact your web hosting provider for more information.

  PHP configuration directive "safe_mode" is set to on

  Safe mode can prevent PHP from writing to the temporary upload folder (upload_tmp_dir). This can cause uploads to fail. To fix this problem, you should ensure that PHP safe_mode is set to "off". If you are unsure about how to do this, contact your web hosting provider for more information.

  PHP configuration directive "open_basedir" is set incorrectly

  This issue can completely prevent PHP from writing to any folder not within the directories (or their subdirectories) specified by the directive. As such, the "open_basedir" directive must either be set to off, or must include the temp directory (PHP directive "upload_tmp_dir") and your web server's document folder (i.e. "/var/www/htdocs"). Note that subfolders of the specified settings can be written to, i.e."open_basedir /tmp:/var/www/htdocs" includes the folder "/var/www/htdocs/social". If you are unsure about how to do this, contact your web hosting provider for more information.

  PHP configuration directive "file_uploads" is set to off

  This directive must be set to "on" to allow any file uploads. If you are unsure about how to do this, contact your web hosting provider for more information.

  PHP configuration directives "upload_max_filesize" or "post_max_filesize" are not set large enough

  This commonly results in the error message "filetype is not allowed". These directives must be set to at least what you have set in the SocialEngine control panel, or larger files will fail to upload. If you are unsure about how to do this, contact your web hosting provider for more information.

  PHP configuration directive "upload_tmp_dir" is set incorrectly or is inaccessible

  The directive "upload_tmp_dir" specifies the folder in which uploads are stored temporarily. It must be a folder that's accessible by PHP. If unset, the default is generally the system temp directory which is a system environment variable (TMP and TEMP are two possibilities). If you are unsure about how to do this, contact your web hosting provider for more information.

  The uploads folder is not accessible

  The uploads folders in the SocialEngine root directory must be writable (aka have full permissions set).

  Linux: You must chmod 777 the folder (recursive)

  Windows: You must set "Full Control" on the folder for the user group "Everyone" (recursive)

  Your web server or client connection is slow and it never finishes or times out (larger files)

  Uploading large files can be tricky sometimes. The best fix for now is to increase your max timeout and upload the file over a reliable internet connection.
