Magento

when go try to download an extenction in magento connect ....
it always says INVALID POST DATA…

WHY ?

i set the write permission to downloader directory.

i’m using XAMPP 1.6.7 and magento 1.1.1 stable

i have the same problem.
it is a bit strange though.
2 websites on 2 servers at the same hosting provider, they say that settings are the same.
on one the downloader works, on one it doesn’t.
i’ve tried with 1.1.1 and the previous version also.
if i use the downloader to install i get PEAR error unknown command ‘install’
if i use the full release, it installs ok, but the connect manager give me the invalid post data error when i try to install any extension.

I have the same problem.
After setting SSH permissions to get the downloader working I input the key into the downloader and get the same error message INVALID POST DATA

i have talked to the tech support for my server and they said that there might be a problem with the PEAR on the server, they will try to repair or reinstall PEAR and after that the downloader should work perfect. will wait and see.

PEAR is fine on my server but I finally managed to find the answer on the wiki…

Worked for me, best of luck everyone, hope that helps.

I’m having this problem too, even when trying the suggested solution.

I’m using Magento 1.1.4 - it’s all installed properly and working. I just can’t get the Download / Connect part to work?!?

Can anybody suggest any alternative fixes?

Thanks

Please!, has anybody successfulyl resolved this problem? I’ve set all permissions to 777 on the entire downloads folder, even all of the files too and i’m still getting this error!??!

Fixed it!! The server filewall settings were too strict, that was my problem.

Umm firewall??
I’ve an magento store under windows xp sp3 and no problem with magento connect.
The same store with the same configuration in apache / php /pear under Windows Vista and… “INVALID POST DATA”

Glups, in windows vista execute internet explorer like admin

Dave has the right answer.

Servers operate behind a firewall so if the software is attempting to connect out to retrieve modules or extensions then it is likely that they will need to allow an exception to allow the outgoing connection.

Your host will need the IP address of the software source.

Hello

You should add exception to allow connection to connect.magentocommerce.com. Remember similar situation happens if you are using some of the payment modules like Authorize.net - you will have to add exception to allow the module to connect to authorize.net server.

I have the same error....

and I disabled the firewall of my server, but the error still there.

I have another installation with a previous version of magento on the same server and the connect dont say “invalid post data”, but doesn’t work.

I’m using plesk on linux.

It’s the worstest error that nobody knows how fix it????

Excuse my english

Admins of magento world show us the light!!!!

Thanks

My host added “connect.magentocommerce.com” as an exception through their firewall and it all work sweet as.

Hope this helps someone else.

My solution was:

Editing the memory limit in .htaccess file in magento root folder to the value of 256M - see example below.

As for adding an exception...my host wants to know what port needs to be open as part of that exception....Any ideas what I should tell them? or does it even matter?

Thanks…

cd
