Debugging Processwire Installation on Ubuntu/Osx

gistfile1.txt

Processwire 500 Internal Server Error

  check site/config.php mysql logins
  check .htaccess

- check if it is read (paste shit in the top)
- check if it works with apache2

Processwire 403 Permission Denied

  sudo chmod -R 777 /var/www/html/project (Attention, not save for live!)
  besser: chmod 755 und für .htaccess 644
  chmod www-data...
  
  fix for `Server unable to read htaccess file, denying access to be safe`:
  look in `/var/log/apache2/error.log`
  sudo chmod +x /path/to/root/folder

Processwire (+ apache2)
can only reach landing page (other pages all 404)

  checken ob er .htaccess erkennt (oben shit rein schreiben)
  check:

- #Options -Indexes
-#Options +FollowSymLinks
-#Options +SymLinksifOwnerMatch

  Rewrite Base:

- /
- /projekt/
- /var/www/html/project
- /home/user/sites/project

  check if 'mod_rewrite' enabled:

- sudo a2enmod rewrite
- sudo service apache2 restart

  try to switch:

- uncomment: RewriteRule ^(.*)$ index.php?it=$1 [L,QSA]
- comment: # RewriteRule ^(.*)$ /index.php?it=$1 [L,QSA]
	-(at the bottom of .htaccess for PW, line 217 and 222, for me)

###Processwire erkennt .htaccess nicht

-> /etc/apache2/apache2.conf

- AllowOverride None -> All
- Require all granted
	- uncomment:   RewriteRule ^(.*)$ index.php?it=$1 [L,QSA]
	- comment:  # RewriteRule ^(.*)$ /index.php?it=$1 [L,QSA]

# wrong template path, root instead of subfolder
[unsolved]
RewriteBase doesn't seem to work.
--> Look in /var/log/apache2/error.log
