I used MantisBT without any problem in the past. After some idle time (~1 year) wanted to check and saw that home page is not coming up. No matter what I do, It is completely blank.
To solve the problem, tried to upgrade as per the instructions on the Admin Guide. Copied the old installation to somewhere else. Unzipped the new version. Copied old config files to the new. Run admin/install.php script. All checks but one is OK.
When I call the URL directly (without admin/install.php), the page comes up with some warmings:Checking URL to installation BAD
Can't retrieve web page at 'https://mantis.xxx.com/'.
What is wrong with my setup? Appreciate any help.Warning: "admin" directory should be removed, or access to it restricted.
Warning: "path" was not defined in config_inc.php. Leaving it empty is a security risk, as the path will be set based on headers from the HTTP request, exposing your system to Host Header Injection attacks.

Thank you.
