[Forum] Post New Thread => white page

[nikosb]

Hi Guys,

some of my users noticed a strange problem: they click on the button "Submit New Thread" und got redirected to a white page (URL: "...newthread.php?do=postthread&f=...")

Note that this does not occur in all publications.
I have vbseo, and open-offs is the same

The Post has no photos or link.

The server has memory_limit 128M


sorry for my bad english. use translate

any ideas?

Here are the common causes of blank or 'white' pages:

1. You did not upload the vB files correctly. Reupload the vB non-image files and make sure you upload these in ASCII format and that you overwrite the ones on the server. Make sure you upload the Admin CP files to the admincp directory specified in your config.php file.

2. You have extra space or lines in your config.php file. Make sure there is no whitespace or extra lines in config.php before the <?php.


3. If this is happening on the forum home page only, then you may have an empty index.html or index.htm file in that directory. Delete it.

4. You have a bad plugin installed. To disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

5. The servername setting in config.php is wrong. Doublecheck this setting. 99% of the time, 'localhost' is correct:

$config['MasterServer']['servername'] = 'localhost';

6. Your PHP has magic_quotes_sybase turned on. You have to turn this off. On *nix systems you can do this by creating an .htaccess file with this content and placing it in your main forum directory:

php_flag magic_quotes_sybase 0

7. [For multiple white pages] You have added code to your header, headinclude or phpinclude templates that is no longer functional.
[For white pages in a select area] You have added code to one of your templates that is causing this problem.

8. You have a corrupted template. Repairing the template table may help:

REPAIR TABLE template;

9. You have GZIP enabled. Try turning GZIP off here:

Admin CP -> vBulletin Options -> Cookies and HTTP Header Options -> GZIP HTML Output -> No

Or by running these queries:

UPDATE setting SET value = '0' WHERE varname = 'gzipoutput';

UPDATE datastore SET data=REPLACE(data,'s:10:"gzipoutput";i:1;','s:10:"gzipoutput";i:0;') WHERE title='options';

You can also add DEFINE('NOZIP', 1); to the top of login.php, or config.php, which should allow you to login.

Sometimes this problem is caused when your server is already using GZIP and by turning this on in vB you were double compressing. This causes problems with some pages but not others. It also happens to some people and not others.

10. Sometimes this can also be caused when PHP has the 'display_errors' function turned off. So instead of displaying the actual error so you can see what is wrong, you get a blank page. Look at your phpinfo page and if 'display_errors' is Off or '0', then add this line to your includes/config.php file right under <?php

ini_set("display_errors", true);

11. Check your phpinfo page to see if suhosin is installed as a module. If it is, this could be the cause of this problem. To fix this, add or edit an .htaccess file in your root forum directory and add these lines to it:

php_flag suhosin.cookie.encrypt Off
php_value suhosin.request.max_vars 2048
php_value suhosin.post.max_vars 2048

[nikosb]

php_flag suhosin.cookie.encrypt Off
php_value suhosin.request.max_vars 2048
php_value suhosin.post.max_vars 2048

and did not enter the forum

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

in the vbacp/Maintenance/View PHP Info
writes this:

Directive Local Value Master Value
suhosin.cookie.encrypt Off Off
suhosin.request.max_vars 500 500
suhosin.post.max_vars 500 500

can blame it?

[Wayne Luke]

500 variables can be too low for some administrative pages. You'll need to contact your host to up that value if Suhosin is causing the problems.

observed that the problem do so when in the Post code exists php, either as a code, either by copy-paste from a source
Post below to try to do editing and add "(" and takes only a blank page

I think the problem started when you turn the WYSIWYG editor in the Message Posting Interface Options
