Big leap upgrade

[AMIGrAve]

Hi,

I've got a site running CMS MS MLE version 1.2.3.

Can I upgrade to 1.6.6 at once (in one operation) or shall I do the 18 upgrades one by one ?

Yes, upgrade straight to 1.6.6.
Just make sure you have backup (files and SQL) in safe place. Also i preferable php5 ( 5.2.11 is good one). Core should upgrade OK. Try upgrade on test site first, because you might have some modules depending on older CMSms.

I've got an Internal Server Error when copying cmsms-mle-1.6.6-full.tar.gz content and going in /install/upgrade.php (php4 or php5 doesn't change)

How can I debug the problem ?

The app is on a shared server and I can't tweak the server config.

Maybe .htaccess rules will work. Does someone knows if there's a htaccess rule that allows to see the php error instead of serving error 500 "Internal Server Error" ?

I finally found out the upgrade problem. It was caused by group write permission on the install folder.

I've now upgraded but the home page now shows a 404 "Not Found" instead of the language selector. Any ideas ?

Why don' t you install on local PC and then move it to shared hosting ?
