The file I downloaded was in the downloads section of this site, SuiteCRM-Upgrade-6.5.x-to-7.0.2
I did look through the pre-requisites pretty carefully, and set the recommended php.ini options.
When I followed the instructions, the upload reached 100% then immediately gives Error 500. Apache access and error log shows nothing, although I do have this directive to turn on error logging: error_reporting = E_ALL & ~E_NOTICE;
What is your Server/PHP/MySQL setup? Have you tried re-setting the recommended permissions? Have you checked your sugarcrm.log for errors? Can you access any page on the CRM?
Sorry, to clarify, my current SugarCRM installation is working fine, but I am trying to upgrade SugarCRM latest version (.16) to SuiteCRM. I have never installed SuiteCRM before.
I run my own VPS with PHP (5.3.3-7+squeeze17) and MySQL v14.14
When you say recommended permissions, do you mean this:
Set the following permissions on the SuiteCRM directory(Linux):
sudo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload config_override.php
?
I just re-set the above (on my existing SugarCRM installation), but still get the same problem.
There’s nothing in my SugarCRM.log file (except this, repeated: Sat Mar 22 17:40:03 2014 [27341][-none-][FATAL] Configuration variable date.timezone is not set, guessed timezone UTC. Please set date.timezone=“UTC” in php.ini!)
