Error 500 After Updating From 1.8 to 1.9.3

[jacobgarcia965]

Hello, 

I am doing a fresh install on my hosting service. 1.8.1 installs perfectly fine, but when i go into the system to update, it gives me an error 500 right after. I have tried several solution, Updating the permissions on the files, removing the HTACCESS file, the way that i am trying to install it is via the Magento Connect Manager using Mage_All_Latest. The errors that pop in right at the end are these: 

CONNECT ERROR: Failed to open file /home1/superdri/public_html/downloader/.cache/community/Interface_Adminhtml_Default-1.9.3.1/app/design/adminhtml/default/default/template/downloadable/sales/order/invoice/create/items/renderer

anyone know of a resolution or work around?

Hi @jacobgarcia965,

That folder is used to download and install extensions through the Magento Connect manager.
Have you recently installed new extensions?

Best,

Gabriel

I didn't have any extensions. I worked around it, did a fresh install of 1.9.3 using cPanel and then magento-cleanup.php for the permissions. Resolved the issue.
