Title: Fixed #019440: Installation failed at Site selection

In my warning.log, this line appeared:

preg_replace(): Compilation failed: POSIX collating elements are not supported at offset 1 in /home/patrice/Workspace/xproject/lib/ezi18n/classes/ezchartransform.php on line 407

Then I added escape character before "." in regex at line 397 and 425 of ezchartransform.php file.
