[pmwiki-users] Path info and GD Graphics Library not found

[Hans]

Hello,
after moving some wiki sites onto a new server (UK provider of shared hosting) I have run into this problem:
I am using the Mini gallery for some photo galleries. Mini is using the PHP GD Graphics Library, and aborts if it cannot find it. After testing and some enquiries with the tech staff I am assured and confident that the GD library is indeed installed and available. 

But it shows as available only on one wiki, where the Gallery page is called with URL  https://example.com/wiki/index.php/Gallery/Gallery
I am using $EnablePathInfo = 1; and index.php simply includes pmwiki.php, which is located in a wiki farm direcory elsewhere. Note this works fine, Mini displays thumb images etc.

But in another wiki, built very similar, it does not work, GD library is not found. The only difference is the URL, https://example.com/web/Gallery/Gallery. Here "web" is a file in the site's root, and it includes pmwiki.php in similar way as the index.php in above example. 
In an .htaccess file I got it configured, that the file "web" is treated as a PHP file, with these lines:

#SetHandler
<FilesMatch "^(web)$">
SetHandler application/x-httpd-php
</FilesMatch>

The wiki displays fine, works fine, but the GD library is not found, and Mini aborts.

I asked the tech staff from the hosting provider for help, but they just say that the GD library is included, and this is a coding problem they cannot or are not willing to address. I thought that I perhaps need to change something in the .htaccess file, but I have no idea.

It may be important to note that the server is not Apache, but LightSpeed (with a Plesk control panel), and I am told it behaves like Apache in the way it interpretes .htacess files.

Has anyone any ideas what I can do to configure the setup, so that a file without php extension can act fully as a php file, including calls to GD library? 

Best regards,
 Hans
