It looks like the page rendering is incomplete. Are there any logs from the web server (PHP errors)?

I think that timeout for generate page

This is most likely a duplicate of 0008538.

Summarizing, see if you are running Zend Optimizer and either disable or upgrade it. Older versions are know to produce this kind of effect

giallu, can you write how I can check from me? I install xampp and I this Zend Optimizer installing too.

just create a test.php file in your web area with the line:

<?php phpinfo();

and open it with your browser. you will be able to see which extensions you have installed and their version.

was resolved by adding

$g_show_assigned_names = OFF;

to config_inc.php
Also experiencing issue 0008537, which appears to be similar behavior.

shared server

PHP version: 5.2.0

MySQL version: 5.0.45-community

Mantis 1.1.6

yeah, but that is a workaround rather than a real solution.

The real solution is to disable or upgrade the Zend Optimizer

I have
Zend Extension 220060519
Zend Memory Manager enabled
This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
report_zend_debug On On
zend.ze1_compatibility_mode Off Off

Is it Zend Optimizer?
If yes, how I can disabled?

I appled patch from 9997 and
Checking Zend Optimiser version (if installed)...
Zend Optimiser not detected GOOD
That's good ;)

yes, that's good...

Rlatorre: the issue your hitting is a buggy php<>zend optimiser combination (it's worth updating zend optmiiser to 3.3

Kirill: Are you hitting the same problem or what exactly is the problem your hitting?

Paul

No, I try check my server for may be future's problems.

rlatorre, this issue seems not to be caused by MantisBT.
Feel free to reopen the issue if there are still problems after upgrading your PHP / Zend optimizer environment.
