Unusal 403 experience

[pdxSherpa]

Hello all hope there is a wp/php expert that can answer this.
Yesterday and partially today i was getting on chrome & opera (not FF) a 403 error when i went to my localhost files.(Did not use to do that)
This morning instead of local host I tried the following:

1. http://127.0.0.1/directory name. worked.
2. in the httpd-xampp.conf

ScriptAlias /php-cgi/ "C:/xampp/php/"
<Directory "C:/xampp/php">
    AllowOverride None
    Options None
** commented out -    Require all denied dlm original line commented out 09/22/15
     Require all granted
    <Files "php-cgi.exe">
          Require all granted
    </Files>
</Directory>

now things are working.
was hoping someone could explain this? or how the 403 came about when everything had been working fine for over a year?
thx

Wordpress can get very weird when you access it through multiple urls. If you are switching between 127. and localhost you might be running into a cache issue. I find a lot of issues like this are cache related, or permissions but you should see an error somewhere for that.

tried it, no such luck, will have to probab uninstall/re-install.
thx though.
