SuiteCRM upgrade from 7.8.6 LTS to 7.10.5 LTS

I tried to upgrade SuiteCRM from 7.8.6 LTS to 7.10.5 LTS by uploading files downloades from SuiteCRM site.
CRM correctly uploaded the files, but when installing, I’ve had a 404 error and now when I go to upgrade session system give me blank page. :frowning:
Suite CRM data and all other features correctly works.

Someone can help me?
Many thanks.

Hi. You probably have a message in your logs explaining what is going wrong.

Most likely - you need to increase some values in your php.ini:

memory_limit (make it 256MB or more)
