Architecture / Installation

Hello,
Interesting that you have a Tiki 6 on PHP 5.5. I have the option set to "No error reporting". Generally all seems to work ok. The specific problem I'm currently having is the display of thumbnails from the image gallery.
Previously we have pages that displayed images inline and then clicking on the would cause them to be displayed in a pop-up box thus {img fileId="184" thumb="y" alt="" rel="box[g]"} . However for some reason the inline display now fails although the pop-up box is ok.
Rightly or wrongly the impression I've formed and also suggested by the host provider is that this is because there is a problem with the version of PHP. The errors quoted above all seem to be related to the image functions or gd library.
Is this something your version has a problem with? Is there something I can do to fix this?

What I think the host has done is to move us to a new server with a new PHP version. So I'm guessing they've sorted out the php.ini files. We don't have access to those.

Thanks Peter
PS I've tried upgrading to 6.14 but this doesn't seem to get rid of the errors.
