+## Php configuration
+
+### Step1 :
+Start with modifying php.ini of your installed Php. You may find php.ini under `/etc/php/{php version}/{apache2 | fpm}/php.ini`. Although if you're not sure where your php.ini is located, you may run the following command to find out:<br>
+```locate php.ini```
+
+e.g.: ```vi /etc/php/7.1/apache2/php.ini```
+
+### Step2:
+Try to modify following variables in php.ini:
+```
+date.timezone = "YOUR TIMEZONE" //e.g. "Europe/Berlin"
+max_execution_time 90
+memory_limit 128M
+session.gc_maxlifetime 14400
+upload_max_filesize 64M
+post_max_size 65M
+
+```
+`upload_max_filesize`: determines the size of files users will be able to upload in filemanager or links.
+
+`session.gc_maxlifetime`: determines the time in seconds of inactivity before a user session will be terminated.
