After some investigation it seems there is something very strange going on with all the paths in my installation.
There’s a line in the QuickEdit code as follows:
if(!isset($mod_path)) { $mod_path = $modx->config[\'base_path\'].\'assets/modules/quick_edit\'; }
Having spotted this I tried setting the ’Module Path’ config setting for the QuickEdit module to blank. This got the QuickEdit file to be finally found by the include_once, but now all the include statements inside
quick_edit\output.class.inc.php
are now failing.
I also tried setting ’Module Path’ for Quick Edit as the full path to quick edit but this also caused late include stmts inside the QuickEdit classes to fail.
THere must be some fuindamental problem occuring with the resolution of certain config paths in my installation, but I cannot for the life of me see what. To make matters worse, I have other, previous MODx sites installed and running with no problems!
Any ideas?
