Connect Manager Issue - Blank screen

[ApsG]

Hi,

On my Magento 1.9.4.2 when I try to log in to the Connect Manager via the admin back end I get just a blank page. The page just locks; it's just a blank white screen.

Curiously, I have another Magento Installation 1.9.3.3 on the same server which works just fine with the connect manager.

I have tried:

• Copying the downloader folder from 1.9.3.3 to 1.9.4.2 but to no avail.

I have also checked :

• File permissions, 
• var folder. etc.  They seem to be fine.
• Checked other similar posts on this forum too.

But nothing seems to work.

This issue seems to be peculiar to 1.9.4.2 because even when I attempt a fresh clean install, the problem persists.

I need the Connect Manager to install extensions the Magento recommended way  and uninstall them cleanly (painlessly) if things don't work out as expected.

Hope someone can shed some light.

Thanks

Hi @ApsG,

Enable error reporting once in index.php

And

Remove connect.cfg from installed_directory/downloader

Remove cache and try once.

I hope it will help you!

Vimal Parihar,

Thank you for your prompt response.

I tried as advised :

- Removed connect.cfg from installed_directory/downloader
- Removed cache (externally)

But now my admin login page from the backend disappeared. It is trying to
connect to my fresh 1.9.4.2 installation that I spoke about earlier (I
guess Magento's famous fallback mechanism at play) and then giving error
404.

How do I get back the log in page ?


Thanks once again

Did you enabled error_reporting from index.php?

Also make sure that you have .htaccass and index.php file under downloader folder.

You can also reset permission using following command.

find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
find ./var -type d -exec chmod 777 {} \;
find ./media -type d -exec chmod 777 {} \;
chmod 777 ./app/etc
chmod 644 ./app/etc/*.xml

You can use sudo if you have sudo user.

Did exactly as advised.

Admin panel comes back partially but with 3 fields ! No CSS

On entering the log in credentials it again goes hunting to the last
installed 1.9.4.2 test store url.

Unable to admin log in.

Ah ! the vageries of magento cache !!!

Verify database configurations once in app/etc/local.xml

And web_url in "core_config_data" once.

Are you using multi website setup?

Hi Vimal,

Finally backend admin panel is kinda restored. Phew !

Unfortunately, in my quest to minimize downtime, the fresh new 1.9.4.2
installation was done using the old database credentials.
The original old installation is a mutistore but not a mutiwebsite.

To restore the admin panel

* I deleted the new store secure / unsecure paths from core_config_data
table
* Deleted var/cache in original installation via ssh
* Deleted var/cache in new 1.9.4.2 installation via ssh
* cross checked app/etc local .xml - found correct

In the database, core_config_table, besides the secure / unsecure paths,
there must be some other entries / records too which need too be deleted.

Any idea ?

Once this is completely fixed back to to the connect manager issue.

Admin Panel issue seems resolved. Thanks for all the help !

Getting Back to Connect Manager issue


- Error code added to index.php in downloader folder but nothing just
blank screen.


- connect.cfg disabled

Following is the error code added at the very top to index.php :

# error reporting code starts here
error_reporting(E_ALL);
$_SERVER['MAGE_IS_DEVELOPER_MODE'] = true;
ini_set('display_errors', 1);

Great... Good to know.

I think you had tried same earlier as I mentioned in previous post, what was wrong that time. Strange.
