We have recently upgraded our site from Joomla 2.5 to 3.4 and PHP to 5.5.
We are having issues where the web browser is saying too many redirects are occuring and not displaying the site.
Also, we are unable to access the administrator area, where it returns a 403 forbidden error.
We use Migrate Me Upgrade to do the upgrade.
Skills: html, joomla upgrade, joomla!, mysql administration, php
