Upgrade from 1.0.8 to 1.2.1 Questions

[perkinsr]

I plan on upgrading our mantis install from version 1.0.8 to the latest 1.2.1

Now I know I will have to upgrade from 1.0.8 to 1.1.0 before I can install the newest. Is there a specific file(s) that I need to backup before doing the install and restore afterwards? One where the database information is stored perhaps? I read through all the documentation but couldn't find any reference to such a file. I do plan on copying the entire folder and doing a sql dump so I can restore if anything should go wrong.

Thanks,
Russell Perkins

Have a look at file doc/INSTALL of your MantisBT 1.2.1 and this old instructions http://www.mantisbt.org/manual/manual.i ... rading.php
ATM there is no chapter for this in administration guide for 1.2

I was able to upgrade from 1.0.8 to 1.1.0 just fine, but when I tried to go from 1.1.0 to 1.2.1 I would just get a blank page. Every page I checked was blank, even the check.php script in /admin/. I also made sure my config_inc.php was correct. I reverted back to the 1.1.0 files and they worked just fine.

Any ideas?

Blank page shows every time you have some syntax error in any of Mantis php files. Including your configuration and customization files.

And there is no easy way to find such error.

I was able to get mantis upgraded to 1.1.8 . However even if I try to do a brand new install of 1.2.1 or 1.2.0 I get the white pages.

Step 1) extact zip
Step 2) sftp upload files
Step 3) white screen

looking in my /var/logs/ I was able to find this error

"PHP Fatal error: Call to undefined function spl_autoload_register() in /var/www/SITENAME/htdocs/mantisbt/core.php on line 136"

I have php PHP 5.2.6
