Gathering info from this link stackoverflow-image save doesn't work with chmod 777 and from user azerafati and Loek Bergman

if you were to look under /etc/apache/envvars file you will see something like:

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data

Apache is run under the username 'www-data'

'0755' means the file owner can read/write/execute but group and other users cannot write. so in ur terminal, cd to the folder containing your 'images' folder. then type:

find images -type d -exec chmod 0755 {} \;
find images -type f -exec chmod 0755 {} \;
sudo chown -R www-data:www-data images

you must change persmissions first before changing owner. enter your password when prompted. this will make 'www-data' owner of the images folder.

your upload should now work.

I know that it is a very old question  but I wanted to add the good solution with some in depth explanation  You will have to execute two statements on Ubuntu like systems and then it works like a charm    Permissions in Linux can be represented with three digits  The first digit defines the permission of the owner of the files  The second digit the permissions of a specific group of users  The third digit defines the permissions for all users who are not the owner nor member of the group   The webserver is supposed to execute with an id that is a member of the group  The webserver should never run with the same id as the owner of the files and directories  In Ubuntu runs apache under the id www-data  That id should be a member of the group for whom the permissions are specified   To give the directory in which you want to change the content of files the proper rights  execute the statement   find  DIR  -type d -exec chmod 770          That would imply in the question of the OP that the permissions for the directory  ROOT  database should be changed accordingly  It is therefor important not to have files within that directory that should never get changed  or removed  It is therefor best practice to create a separate directory for files whose content must be changed   Reading permissions  4  for a directory means being able to collect all files and directories with their metadata within a directory  Write permissions  2  gives the permission to change the content of the directory  Implying adding and removing files  changing permissions etc   Execution permission  1  means that you have the right to go into that directory  Without the latter is it impossible to go deeper into the directory  The webserver needs read  write and execute permissions when the content of a file should be changed  Therefor needs the group the digit 7   The second statement is in the question of the OP   find  DOCUMENT ROOT  database -type f -exec chmod 760         Being able to read and write a document is required  but it is not required to execute the file  The 7 is given to the owner of the files  the 6 to the group  The webserver does not need to have the permission to execute the file in order to change its content  Those write permissions should only be given to files in that directory   All other users should not be given any permission   For directories that do not require to change its files are group permissions of 5 sufficient  Documentation about permissions and some examples   https   wiki debian org Permissions  https   www linux com learn tutorials 309527-understanding-linux-file-permissions  http   www linux org threads file-permissions-chmod 4094

Try adjusting the directory permissions   from a terminal  run chmod 777 database  from the directory that contains the database folder   apache and nobody will have access to this directory if it is chmodd ed correctly   The other thing to do is echo  getcwd     This will show you the current directory  and if this isn t   something    database   then you ll need to change  query txt  to the full path for your server

The other option is that you can make Apache  www-data   the owner of the folder sudo chown -R www-data www-data  var www  that should make file put contents work now  But for more security you better also set the permissions like below find  var www -type d -print0   xargs -0 chmod 0755   folder find  var www -type f -print0   xargs -0 chmod 0644   files   change  var www to the root folder of your php files

Realise this is pretty old now  but there s no need to manually write queries to a file like this  MySQL has logging support built in  you just need to enable it within your dev environment   Take a look at the documentation for the  general query log    http   dev mysql com doc refman 5 1 en query-log html

If you are pulling from git from local to server  you will need to clear cache sometimes because of the view files it gets uploaded with it   or other cached files    php artisan cache clear   Sometimes it might just to the trick if your application was working before the git pull
