I have many questions

Does your PHP have the GD extension enabled? Do you get any errors in your web servers error logs?

Thank you for your rapidity, I'm on Host Mutualist 1and1 and I don't know how to view server's logs. In the admin panel, I have these informations:[quote]System infoYou have PHP version: 5.2.17GD Library version:Array( [GD Version] => bundled (2.0.34 compatible) [FreeType Support] => 1 [FreeType Linkage] => with freetype [T1Lib Support] => [GIF Read Support] => 1 [GIF Create Support] => 1 [JPG Support] => 1 [PNG Support] => 1 [WBMP Support] => 1 [XPM Support] => [XBM Support] => 1 [JIS-mapped Japanese Font Support] => )[/quote]

Well I am not familiar with 1and1 (I hear they are terrible) but maybe some folders aren't writable or something. There was a report here about black images: https://milliondollarscript.com/installation/documentation/docs

I don't have this problem in admin area, all folders are writable... before there was not the black background but I certainly made a mistake.edit: I have an error when I click on "view pixels" in pixels admin:"The image "http://the-wall.fr/admin/show_map.php can not be displayed because it contains errors."The problem is probably here.

Hmm, I think you have to figure out whats in the error logs for your web server. Maybe PHP is running out of memory or something. You could try raising the memory limit in the Main Config.

I'm already at 64 MB, I also noticed that the PNG conversion does not work and that the JPG conversion did not display images. All this may be linked.I find server's logs but I don't know what should I watch.[u]edit:[/u]1and1 does not provide access to apache logs errors for shared hosting customers, they are simply a piece of code to generate our own errors logs. I'll try that and I'll keep you informed. Thank you again

Here is the error_log generated:[code]18 Feb 2011 23:54:06,"/homepages/0/d224845791/htdocs/wall/test/config.php: 127","(Notice) Undefined variable: DB_ERROR"18 Feb 2011 23:54:06,"/homepages/0/d224845791/htdocs/wall/test/lang/lang.php: 24","(Notice) Undefined index: lang"18 Feb 2011 23:54:06,"/homepages/0/d224845791/htdocs/wall/test/lang/lang.php: 44","(Notice) Undefined variable: _SESSION"18 Feb 2011 23:54:06,"/homepages/0/d224845791/htdocs/wall/test/lang/lang.php: 47","(Notice) Undefined index: MDS_SAVED_LANG"18 Feb 2011 23:54:06,"/homepages/0/d224845791/htdocs/wall/test/mail/smtp_message.php: 594","() Declaration of smtp_message_class::SendMessageBody() should be compatible with that of email_message_class::SendMessageBody()"[/code]

It looks like maybe the error reporting is messing it up or something. Set your error reporting to off. Those errors should be just harmless notices. However, if they are causing problems you might have to turn off the error reporting somehow. I have no idea how to do this on 1and1.

FYI, this is the error reporting I am referring to. It is in the php.ini. You can also sometimes set it in the php file itself (I think it might even be set in MDS, I can't remember) and sometimes the htaccess.http://www.php.net/manual/en/errorfunc.configuration.php reference for the SMTP error from the mail lib being used in the script: http://www.phpclasses.org/discuss/package/9/thread/75/

This is my PHP CORE Configuration:[url=http://www.id-f.fr/upload/php-core.jpg]http://www.id-f.Fr/upload/php-core.jpg[/url]If it can help.edit: I did a fresh install and everything seems to work, I had to make a mistake somewhere. I'll keep you informed and thank you again for everything

It seems that the errors happens when I change the block size in 25x25 instead of 10x10. When I return to 10x10 all working again perfectly but is too small to be I want to do.[u]edit:[/u] I found where was the problem with the black background. After for the rest I think it's linked at the changement of size of my blocks.This is the URL of my page if you want watch it: [url=http://www.the-wall.fr]http//www.the-wall.fr[/url]

You would have an idea ..?

Hi, sorry for the delayed response. Did you still have a problem? Or are you just saying there is a problem changing from the 10x10 to 25x25? If so please could you explain more about the problem and what you have tried and if you have fixed it?
