I'm running Magento 1.7 on php6.5, which was previously on php5.3.
First problem, Deprecated functionality: iconv_set_encoding(), was solved with this: Magento 1.9, php 5.6 - Use of iconv.internal_encoding is deprecated
Now I've got a new error message:
ini_set(): Cannot find save handler 'memcache' in /var/www/rkbridal/app/code/core/Mage/Core/Model/Session/Abstract/Varien.php
How to work through this?
