Installation: Links from Website to Gallery and Admin Log-in producing a install or update screen.

My links from my webpages to my gallery are displaying a screen asking for install or upgrade. I've contacted my Webhost and asked them to look at the problem and received following response:

Hi Joe, I have attempted to take a brief look at the software to try and advise. The issue is that when the system is checked on loading the site (index.php) calls plog-load-config.php and ends up with.... >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Check if Plogger is installed first if (!is_plogger_installed()) { if (isset($_SERVERREQUEST_URI?) && strpos($_SERVERREQUEST_URI?, 'plog-admin')) { $install_url = '_install.php'; $upgrade_url = '_upgrade.php'; $img = ; } else { $install_url = 'plog-admin/_install.php'; $upgrade_url = 'plog-admin/_upgrade.php'; $img = ; } die($img."\n" . ' '.plog_tr('Please run _install.php to set up Plogger. If you are upgrading from a previous version, please run _upgrade.php').'.

'); } <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< It is the 'else' statement that is being invoked, then printing the screen you see via the 'die' statement - In essence, that block of code is checking for the plog install and thinks its not and hence offers the option to install. I can't progress much further as there is no indication of server or permission errors etc, You could now search the plog site forum for issues related per the above - although in most cases it normally requires a later version software install/upgrade - but the plog forum may shed more light on your specific problem. Just some pointers, are you running a beta version, maybe not the latest known working release, and if you do upgrade or reinstall - will you need to drop your database, or does the plog install do that for you - an overwrite of an old databse would probably cause issues - all points you may wish to consider.

I have been using Plogger on webhost server since May2010. This probem occurred last week during an upload of new images session.
Can anyone advise me on solutions? I've put this on the Trac tickets but not sure how much or how often support is available (Ticket #263 refers)

Thanks, Joe Molloy
