  • most probably it's the issue of your virtual server configuration. Please let us know which virtual server do you use? Or if you know how to read error.log - read it and post here last values

I'd prefer to use n98-magerun https://github.com/netz98/n98-magerun

By one simple command you can disable/enable/clean cache via console and much much more.

  • Sorry maybe I didn't understand your question initially. They mean disable cache any way you like. It can be via admin area or via database or somehow you like
