I don't know I should post this on Magento community site or Ubuntu community site, so I am posting here.
I had PHP 5.3 installed.
I upgraded to PHP 5.5, but for some reasons had to revert back to PHP 5.3.
ISSUE:
I have Magento and Codeigniter website on server. From now on, whenever I try to save image from website's dashboard, either Magento or CI, I get folder is not writeable
like error.
Then I checked online for solution and I found that Apache user should be owner, so I ran chown -R apache:apache /public_html on server. This solved images issue, I was able to save images from website's dashboard.
But there is another problem, when I checkout on my Magento website I get this error.
Do I need to install Apache all over again? or what should I do?
