[jignesh-baldha]

Preconditions

1. Magento Version 2.2.4
2. PHP Version 7.0.30
3. MySQL version 5.7.22
4. Apache/2.4.18 (Ubuntu)

Steps to reproduce

1. I've installed latest Magento ver 2.2.4
2. Module Manager doesn't show module grid when going through below step:

• System > Tools > Web Setup Wizard > Module Manager

Expected result

1. It should show manage module grid.

Actual result

Console shows following error
GET http://127.0.0.1/magento224/setup/index.php/moduleGrid/modules 500 (Internal Server Error)

I too am able to reproduce this.

Hi guys, can you please take a look in the log files of your webserver (apache/nginx/...), because "Internal Server Errors" are getting logged over there. Those log files will probably give you more info about what's wrong.

[DigitalStartupUK]

Nothing in Apache logs is being generated. I can't do a deep dive in this instance as I'm looking at a Shared Hosting Account that I use for Sandboxing. I don't particularly want to try and reproduce this on my Production/Dev Dedicated servers. Perhaps @jignesh-baldha can produce logs.

I am having same issue on Fresh Install of Magento CE 2.2.4 with PHP 7.1.6

JS is No Where (500) for ....../setup/index.php/moduleGrid/modules

Facing the same issues using Magento CE 2.2.4 & PHP 7.0.28

@hostep , No logs in apache.

[jignesh-baldha]

@hostep Not found any error in apache logs.

[hostep]

Ok, and how about the log locations of your Magento installation, for example in:

• var/log/
• var/report/

Also: if you take a look in your inspector to the network tab and you see that request which throws a 500 error, can you take a look at the response if something interesting is in there?

Fresh Magento CE 2.2.4 install with PHP 7.0.25 + Apache 2.4.29.
Same error as all above.
No logs in apache or in Magento. No report in Magento.

The console error message goes a bit further, though:

You guys can get further than I can. I get HTTP ERROR 500 when trying to just access the Web Setup Wizard on 2.2.4. I updated via composer.

Could this be anyhow related to issues #4546 and #4575 ?

[rishabhchd19]

same problem here.

Hi guys, I just saw this PR which seems to fix this problem: #15211
Can someone confirm that changing that one line fixes the problem? Thanks!

[DigitalStartupUK]

@hostep I can confirm that this does "fix" the issue. Looks like it's down to the new Amazon Pay component (amzn/amazon-pay-and-login-magento-2-module). But this shouldn't be considered an actual fix for anyone thinking about changing the core code.

Thank you by-the-way, @hostep
