Can't upgrade to 2.5 The connection was reset

[Faisal]

Hi all

I have website A (ProcessWire 2.4.0) in server A (Dedicated Servers)

And

I have website B (ProcessWire 2.4.0) in server B (VPS)

Both websites are multi-language using (Languages Support, Languages Support - Fields and Languages Support - Page Names) modules.

Both servers are:

Apache 2.2.25
MySQL 5.5.31
Php 5.3.27

I want to upgrade website A to (ProcessWire 2.5.x) I get massage from browser after uploading wire folder, htaccess and index file

I get browser error and nothing else.

I get in FireFox:

The connection was reset

The connection to the server was reset while the page was loading.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

And from Chrome:

No data received

ReloadHide details
Unable to load the webpage because the server sent no data.
Error code: ERR_EMPTY_RESPONSE

Tests:

1. I copy website B to server A and try to upgrade (same problem)
2. I copy website A to server B and try to upgrade (it works)
3. I copy website A to localhost and try to upgrade (it works)
4. If upload website A from localhost after upgrade (it works)
5. I upgrade website B in server B (it works)
6. I Install PW 2.5 in server A, if choose "site-languages" profile (same problem) install not continue after select languages profile
7. I Install PW 2.5 in server A "site-blank" profile then install (Languages Support, Languages Support - Fields and Languages Support - Page Names) modules. and start adding some test Language fileds (it works)

Thanks in advance

check if your old .htaccess has been changed during the upgrade

[Faisal]

Yes, I did that

I also try to use old .htaccess just to check if the new one is making this problem but it seems not.

@Faisal - not sure if this will make a difference, but have you tried the Upgrades module?

[Faisal]

No, I see it still beta, and the upgrade steps are very easy.

And by the way there are no any 3rd party modules installed in any of the websites.

This might help:

I read this before, not helping.

I am now comparing both server configuration and I see thy are almost identical, unless I am missing something.

[Faisal]

In Apache Error Log I got

[notice] child pid xxxxx exit signal Segmentation fault (11)

every time I visit homepage or admin page after uploading PW 2.5 upgrade files.

xxxxx = random number

[Faisal]

OK, I don't know if this is the fix but this what happend

I comment the zend extensions at the end of php.ini file

./build ioncube

./build zend

restart Apache

(same problem)

Then

I comment the zend extensions again at the end of php.ini file

Delete both ZendGuardLoader.so and ioncube_loader_lin_5.3.so files

./build ioncube

./build zend

restart Apache

(it works)

Any body have an explanation or should I mark this as Solved

Any body have an explanation

If somehow you are dealing with ioncube, then this was not a PW related issue.  Glad you finally got it working.

Yes, it's not PW related issue. that's what was driving me crazy!!! and I knew that since day 1 of this problem.

And I don't like just fixing the problem, I always like to know what and why cause this and that.

By the way I didn't figure it out the solution my self.

I google the Chrome error message and all I can find is:

1- This is an Apache related issue.

2- Some people say to install gdp for debug Apache and here is one of them http://sysadmin.carlusgg.com/?p=197

3- Some people say disable all PHP extensions, if the error is disappear, enable theme one by one until you find the one causing this.

Since I have only have ioncube and zend only,

I try my luck with ioncube and zend and it's worked for me so I post my experience with it here so it may be helpful to somebody else.

Thank you all.
