Soap Error: Error Fetching http headers

I use Round Cube on my server and I have some problem. In section Settings>Account when I try use some option I see error:

Soap Error: Error Fetching http headers

It seems happend when I upgrade php to 5.2.13.

Do you have any idea how to fix it?

 

Can you try this? http://stackoverflow.com/questions/...p-error-fetching-http-headers/1152603#1152603

 

Yes I tried to change default_socket_timeout = 120 and default_socket_timeout = 480,
restart apache. It did not help.

 

Do you use a PHP opcode cache such as eAccelerator, APC, or Xcache? If so, you might have to update that as well.

 

I do not use eAccelerator, APC or Xcache.

 

Maybe some other PHP-related software that needs an update as well?

 

I have all stable packets up to date on my debian lenny. Do you konow may be how to debug this error? I can not find any information in logs.

 

How did you upgrade to PHP 5.2.13? Because for Lenny, the PHP version in the repositories is 5.2.6.

 

I downgrade php to 5.2.6 version but this did not solve the problem

 

Did you check Apache's error log?

 

yes and there is no errors, so I think that script is ok and it can be problem with header encoding or header is send two times for example

 

I'm running out of ideas...

 

ok so I will have to check a little in this round cube plugin for ispconfig, may be I find the problem.

 

Has anyone found the solution???
