Magento

hi, after i’ve updated our magento store to version 1.2.0.1 i can’t access magento connect. Frontend and backend works fine after i’ve fixed a few issues, but when i click maggento connect from admin this is what i get:

Fatal error: Call to undefined method Mage::isinstalled() in /data/www/dvdautoradia.cz/www.dvdautoradia.cz/downloader/Maged/Controller.php on line 384

i’ve tried to put there the whole downloader folder from my backed up 1.1.8 version, that worked but there was nothing in the list where should be the versions atc…

some clues?

thanks!

I encountered exactly the same fatal error when trying to access Magento Connect Manager.  Yesterday, I followed the instructions on http://www.magentocommerce.com/wiki/upgrade_using_magento_connect:

In the admin go to System/Magento Connect/Magento Connect Manager

Paste magento-core/Mage_All_Latest into Paste extension key to install:, then click Install

You may get a message like this(and more) in the pear window below

magento-core/Mage_All_Latest requires package “magento-core/Mage_Core_Modules” (version >= 1.1.8, version ⇐ 1.2, excluded versions: 1.2), installed version is 1.1.6

At the far right of Manage Existing Extensions click Check for Upgrades

Rows of packages with available upgrades will now be yellow.

Chose the latest version in every rows select.

Now click Commit Changes.

Now again, paste magento-core/Mage_All_Latest into Paste extension key to install:, then click Install.

After the first step, I had unpacking errors:

ERROR: unable to unpack C:\wamp\www\mywebsite\downloader\pearlib\download\Lib_LinLibertineFont-1.1.1.tgz

install ok: channel://connect.magentocommerce.com/core/Mage_All_Latest-1.2.0.1

Then I followed the next step and clicked on “Check for Upgrades” and immediately I received the fatal error:

Fatal error: Call to undefined method Mage::isinstalled() in C:\wamp\www\mywebsite\downloader\Maged\Controller.php on line 384

The frontend and backend do not seem to be affected. But every time I try to access Magento Connect Manager, I have the same fatal error. Anyone knows of a way to resolve this. Thank you.

Well, actually, the backend is not working too well.  I can’t save and I can’t load images in product edit. Now I can’t do any work anymore.

i just tried upgrading from 1.1.8 to 1.2.0.1 and recieved the same error as the first post. Now in the backend i get a bunch of 404 error page not found. my front end is all messed up...Anyone know of a fix?

Thanks

Hi All,

I had the same issue, turns out in the end for me it was file permissions. check your apache error logs from your host if you can. I should of done that A LOT EARLIER. dang hosts these days… i much prefer my local server and actually showing errors when they happen mid request .

Also,

check out the pear.ini file in /downloader/pearlib/

It could be that the path names to the pear modules are not right (ex they are a local server path for testing or something).

regards.

wow… i get the same error but i didnt even get to update it. I uploaded the 1.2 files into the downloader directory, went to the magento connect screen and out pops this error. Fatal error: Call to undefined method Mage::isinstalled() in /home/kingkong/public_html/danielsondirect.com/downloader/Maged/Controller.php on line 384

do you need to upgrade 1.1.6 to 1.1.8 before going to 1.2??

i dont think that upgradeing to a differend version will take any effect.
as far as i understand “theapokalypsis” the error is related to insufficant file permissions, which will not be checked befor updateing.

Is it possible to replace the files by hand?

i think i found a solution which i described here:

How to fix it DIRTY!

Its with as much warning signs as possible but i thems to work. Backup your Files and the Database befor your try. NO Guarantee !

Just to let you know, I ended up installing 1.1.8 and it worked fine. 1.2 didnt work for me.  I didnt need to change anything to get 1.1.8 to install. Now that 1.1.8 is installed ... I will try 1.2 when I get around to it.

It seems that the upgrade does not complete sometimes. I had this error, too, so I went to

/downloader/Maged/Controller.php

replace with

(so you can put this back when fixed)

i then got the same error for another class
/downloader/Maged/Session.php

replace with

I then could access Magento Connect and I reran the upgrade - magento-core/Mage_All_Latest and Install

I put back the above code and it all seems to be working now.

Hope that helps!

techgryll, thanks for the advise on the panel, it helped to a certain extent but have a few questions:

1) Fatal error: Call to undefined method Mage::isinstalled() in /var/www/vhosts/inkinkink.ca/httpdocs/estore/downloader/Maged/Model/Session.php on line 34 is the current error i have and I dont quite know how to insert the

return true;; clause in an if statement. I tried nulling out the whole if statement and replacing it with the return true clause and it still does not work.

Furthermore, I was not able to locate /downloader/Maged/Session.php but was able to locate the Session.php in /downloader/Maged/Model/Session.php , am I in the right place for this? Please advise. Thanks for all ur help!
