Thanks for the advise!

It turned out that the problem was caused by another widget which was actually 2 “slots” above the meta widget in the 2nd sidebar. Removing this widget makes the meta widget appear again. In turn, this widget prevents whatever other widget I put into this slot, 2 below it, to work…weird.

The problematic widget is from a gallery plugin, randomly displaying photos. I’ll see if other people have problems with this plugin.

For now at least the solution is no photos, but access to registration and login 🙂

Hi

I solved the problem for myself, but I am not sure if there is a bug in the code in general.

In the file nggfunctions.php, inside the function ‘nggSinglePicture’ the actual ‘<image src=>’ for showing the picture is created in two ways:

1) If you have image caching deactivated (which was the case for me) the image tag is created by calling nggshow.php in the way shown in my previous post. At least in my case the replacing of ‘&amp’ with ‘&’ does not work correctly and this fails.
2) If image caching is active, it is only used on published pages (i.e. in the if clause checking for image caching there is also a check if the page being created is published). In my case, I wanted to use unpublished pages as subpages (so that they dont appear in the pages sidebar), so that this method also did not work. I removed the check for publish/unpublished from the if clause and now everything is fine.

I hope this helps. I dont know exactly when to use &amp for &, but there seems to be a small error in the line that uses this command.

Thank you very much for a terrific plugin!

Hi again
my progress is limited…but I am learning alot about php at least. So here is what I know now (also, the info in my last post has been slightly incorrect)

1) GD library is not loaded by default on my server, but can be added by
extension = gd.so
in the php.ini file. Somehow the settings on this server (as far as I could figure it out) require that such a php.ini file is placed directly into the folder from which the script in question is run.
This I have tested with the small test script:

$array=gd_info ();
foreach ($array as $key=>$val) {
if ($val===true) {
$val=”Enabled”;
}
if ($val===false) {
$val=”Disabled”;
}
echo “$key: $val
\n”;
}

As soon as a php.ini with the above mentioned line is in the same folder, this script works and lists the GD settings. But it really only works if php.ini is in the folder.

2) Thinking that this might be my problem, I have copied the php.ini created by WordPress into each and every folder that contains php-files, both of the WordPress installation and the NGGallery plugin.
As a consequence, the test script now works in all of these folders.

3) I went further and tested the GD functions with an example from the php-manual:
header (‘Content-type: image/png’);
$im = @imagecreatetruecolor(120, 20)
or die(‘Cannot Initialize new GD image stream’);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, ‘A Simple Text String’, $text_color);
imagepng($im);
imagedestroy($im);

This works also in all the NGGallery and WordPress folders.

4) When I now click on the Gallery tap in the WordPress admin (the link opened is ./wordpress/wp-admin/admin.php?page=nggallery)
I still get the “No GD support” line.
My last post was incorrect that
if(function_exists(“gd_info”))
returns true elsewhere in the file that creates this page (overview.php). In this script it does not work anywhere.

5) My idea was that probably the script that produces the shown output (overview.php) is in practise not executed from the folder where it is stored but from somewhere else. Hence I copied the required php.ini to each and every folder in the WordPress installation, but it does not change anything.

I still suspect that this is my problem, somehow the NGGallery code is executed within WordPress in such a way that the php.ini files with extension = gd.so are not used.
Here my (very limited) php knowledge is long exhausted. I have no idea if and how this is possible and how it could be fixed.

Any ideas?

Hi

I promise this is the last time I answer to my own post 🙂

I have looked at the npgallery code now. When I select the Gallery tap in the WP admin, the file /npgallery/admin/wp25/overview.php is loaded (why the wp25 and not the one in /npgallery/admin/ ?)

In this file there is a function ngg_gd_info() which checks for GD support:
if(function_exists(“gd_info”))
{echo ‘<h4>’.__(‘GD support’, ‘nggallery’).'</h4><ul class=”settings”>’;}
else {echo ‘<h4>’.__(‘No GD support’, ‘nggallery’).’!</h4>

‘;

I keep seeing “No GD support” in the admin tap.

Now I wrote a php script
if(function_exists(“gd_info”))
echo “it EXISTS”;
and placed it in the same folder…and what do I get? it EXISTS

I am totally lost how this is possible. Any ideas anyone?
