Blank page after login with Magento Connect Manager

[chip13]

Hi,
I moved my version of PHP to version 5.6.25, I deleted the files to delete yet, but the blank page is still there.

I even tried to disable the module "Mage_AdminNotification" via "system / configuration / advanced" in addition to my plugins, and I always have the same message in the log "system.log"! It's surprising, is not it ?

For SSH access, with my host, is not possible with a shared server, unfortunately for me.

after you disabled the module did you remove the cache and sessions locks in /var/

[drillsar12]

also go in /app/etc/modules and see what modules in there; you can disable those by looking for  line <active> making it false; I would do this for all them except the Mage and CMRedission modules than remove /var/cache again

Figure it out?

Hello,

Sorry, I was away for a few days.

Yes, I had cleared the "cache" and "session" folders after disabling the modules.

Here, I just disable them by putting "false" in place of "true" in each module file of "app / etc /". Unfortunately no change, always my blank page.

Should I still leave Debug Profiler set to Yes ?

Thank you in advance

Ok you may have to install a new one. You can do that on another host or make a folder inside your magento called fresh. Copy parts of your old database to it, etc.

Actually try going inside var folder and delete cache folder, session folder. Is there any php_error log?

Hi!

In my case I just change downloader/template/login_.php to downloader/template/login.php and now it works!

After use downloader I recommend you disable downloader to avoid malicious access.

Hello and thank you for your help,

I just checked and I do not have a file named "downloader/template/login.php" by cons I have a name "downloader/template/login.phtml".
Have you been deceived and are you talking about this?

Hi @chip13, just cheking as its not mention here, you rember to check that the maintenance.flag file in top of your web folder doesnt exist? Sometime its not deleted automatically .

I'm sorry to hear about the trouble you're facing with Magento Connect Manager. It's frustrating when technical issues like this arise. Considering the persistent blank page after login, it might be related to a conflicting extension booster de or a server configuration problem. Have you tried checking error logs for any specific messages? Also, for the plugin installation, a manual install could be an alternative if the Connect Manager continues to pose issues. Make sure to follow the instructions carefully. Wishing you a speedy resolution!
