Readiness Check

[teemingpl]

Hi guys, I just pulled the latest code and tried to install Magento 2 on MAMP. However, I am blocked at the readiness check:

PHP Version Check: Server failed to respond. Please try again.
PHP Settings Check: Server failed to respond. Please try again.
PHP Extensions Check: Server failed to respond. Please try again.
File Permission Check: Server failed to respond. Please try again.

Any idea what I am missing? Thanks

Hi @teemingpl ,

sorry about that. Please, try to check response using browser's debug window to see detailed errors.

We're working on fixing detailed messages for errors in the Readiness Check.

Internal ticket MAGETWO-43039

[teemingpl]

I'm getting 500 (internal server error) for all four checks

[cscarnell98]

@vpelipenko fails for me with nginx and php 7.0 RC4

We closed MAGETWO-43039 as it was a duplicate of MAGETWO-43385

@craigcarnell do you still have this issue? anyone else has this issue?

[mazhalai]

Closing since this has been fixed in 2.0.0

[EdIzotov]

I get the same issue in 2.0.0 (with the same stacktrace)

[mazhalai]

@EdIzotov please refrain from posting on closed issues. Please create a new issue. Can you give more details about your environment and how did you deploy magento2?

[raqy]

I got the same errors on magento 2 stable (cloned from github). 500 internal error for all 4 checks :-(
i'm on php 5.5.16
