I get an HTTP ERROR 500

If the plugin is disabled, the error does not show up.
However, i Have installed Price compare plugin but if i upload Visual composer plugin page don’t show up.
I don’t think problem is with plugin when i **pre installs ** visual composer plugin page works well but as if i try to install second plugin Price compare error shows up. #maybespaceError
Please help

It sounds like the plugin is broken. You could try to enable error reporting to figure out the actual issue: https://infinityfree.net/support/http-error-500
