Just installed 2.6, and ran into a 'problem' on my system (OpenVMS):
Earlier versions installed and ran out-of-the-box, since the only dot in a filename was the delimietr between filename and extension. 2.6 however has one within the filename - and these are replaced by "_" by the system (though dots are accepted...): It concerns the following files:
These files are loaded in script-loader.php
I solved the problem by renaming the files (using "." in stead of "_") but would like to suggest to use "-" "(or "_") in stead of "." in a filename. It allows flawless install on this system.
