+assistance. Friendica will not work correctly if you cannot perform this step.
+
+You should also be sure that $a->config['php_path'] is set correctly, it should
+look like (changing it to the correct PHP location)
+
+$a->config['php_path'] = '/usr/local/php53/bin/php'
+
+Alternative: You may be able to use the 'poormancron' plugin to perform this
+step if you are using a recent Friendica release. 'poormancron' may result in
+perfomance and memory issues and is only suitable for small sites with one or
+two users and a handful of contacts. To do this, edit the file
+".htconfig.php" and look for a line describing your plugins. On a fresh
+installation, it will look like
+
+$a->config['system']['addon'] = 'js_upload';
+
+This indicates the "js_upload" addon module is enabled. You may add additional
+addons/plugins using this same line in the configuration file. Change it to
+read
+
+$a->config['system']['addon'] = 'js_upload,poormancron';
+
+and save your changes.

+ This could be the result of one of our Apache directives not being

+you are using a Windows server as this has been known to cause problems.
+Also check your file permissions. Your website and all contents must generally
+be world-readable.
+
+ It is likely that your web server reported the source of the problem in
+its error log files. Please review these system error logs to determine what

+
+ First check your file permissions. Your website and all contents must
+generally be world-readable.
+
+ Ensure that mod-rewite is installed and working, and that your
+.htaccess file is being used. To verify the latter, create a file test.out
+containing the word "test" in the top directory of Friendica, make it world
+readable and point your web browser to
+
+http://yoursitenamehere.com/test.out
+
+ This file should be blocked. You should get a permission denied message.
+
+ If you see the word "test" your Apache configuration is not allowing
+your .htaccess file to be used (there are rules in this file to block access
+to any file with .out at the end, as these are typically used for system logs).
+
+ Make certain the .htaccess file exists and is readable by everybody, then
+look for the existence of "AllowOverride None" in the Apache server
+configuration for your site. This will need to be changed to
+"AllowOverride All".
+
+ If you do not see the word "test", your .htaccess is working, but it is
+likely that mod-rewrite is not installed in your web server or is not working.
+
+ On most flavour of Linux,
+
+% a2enmod rewrite
+% /etc/init.d/apache2 restart
+
+ Consult your hosting provider, experts on your particular Linux
+distribution or (if Windows) the provider of your Apache server software if
+you need to change either of these and can not figure out how. There is
+a lot of help available on the web. Google "mod-rewrite" along with the
+name of your operating system distribution or Apache package (if using
+Windows).
