403 Forbidden

There is an obscure but persistent issue with Apache on Windows causing a 403 forbidden error.

Basically Apache won't allow the : in the URL that works on other systems due to a security concern based on the fact that windows paths can have colons in them: C:\some\path.

We have addressed this by providing a configurable option for the parameter separator that is defaulting to :

Simply edit your user/config/system.yaml and add this at the top:

param_sep: ';'

This will configure Grav to use a semicolon, rather than a colon for parameters such as http://yoursite.com/blog/tag:something will now be: http://yoursite.com/blog/tag;something.

403 issue in Admin

If you have mod_security installed, we had reports of rule 350147 (http://wiki.atomicorp.com/wiki/index.php/WAF_350147) triggering a false positive. Whitelist that rule, or ask your hosting provider support to do it.
