upgrade problem from version 1.5.2+ to 1.8.1+ (via 1.7.2)

After testing 1.8.1 on a backup server, yesterday I upgraded my main site from 1.5.2+ to 1.8.1+.

Everything went well going from 1.5.2+ to 1.7.2 No errors were reported and the brief checks I did seemed to indicate everything was fine. I migrated the database without any problems.

I then upgraded to 1.8.1+(2007021510). I set it to unattended mode but watched anyway. Most of it went OK but I saw a database upgrade error appear but then disappear before I could properly read it. The next screen was a blank page.

I shut my browser down and then restarted it. I logged on as admin OK and the site seems to be working without any problems except that if I choose "notifications" from the 'Site Administration' I get a blank page again.

Is there an installation log somewhere that might tell me what has gone wrong?

Hi John,

server (error) logs might tell something but you could also try to turn debugging on from

Administration -> Server -> Debugging
Debug messages: ALL

and go to Notifications.

Did you have anything installed outside "normal" 1.5 package? I could guess something "old from 1.5" is missing/not upgraded or lack of memory could be one explanation...

John - In your moodledata folder look for a folder called upgradelogs and there should be a series of html files that show what happened. Peace - Anthony

It appears that the install failed after the authorize plugin had been updated as this is the last entry.

authorize plugin needs upgrading

authorize tables have been set up correctly

Thanks Anthony.

I have the same error.

I have recently upgraded Moodle from 1.6 to 1.8. Everything had worked fine. I installed numerous blocks and they all worked. At first when I went to the administration page and clicked on notifications, there was a completely blank white page. Later it fixed itself. I am not sure how.

But now it is doing the same thing. I cannot install modules because the notifications page is always blank.

If any of you know the answer to this, please respond.

Hi Paul,

My problem was that in Moodle 1.5 there is a folder moodle/enrol/internal

In Moodle 1.8 this is no longer present but the upgrade process can add new files and overwrite old files but cannot (or does not) delete files so you have to remove this folder manually.

This cured my problem.

Hope this helps.

John

Hello,

I have the same problem. By clicking on notifications as an admin I get an empty page. Only when I delete the line upgrade_RPC_functions in admin/index.php I get a correct notification page. Can somebody help me?

Thanks,
Katarzyna Potocka

KP (&PB),

In his last post in this thread, JR indicated that his problem happened because he put the upgraded Moodle files into the same folder as the old version (see http://docs.moodle.org/en/Installation_FAQ#How_do_I_upgrade_Moodle.3F_Do_I_just_overwrite_the_files.3F). You didn't do that, did you?

No, don't think so smile

it has something to do with a new impleneted enrolment possibility. When I change the moodle code in admin/mnet/adminlib.php so that he dowsn't look for this special enrolment type it works fine. Can somebody tell me, what for the upgrade_RPC_functions() in admin/index.php are.

Thanks, KP

KP,

Vaguely. According to the (very terse) comments in admin/index.php, the function upgrade_RPC_functions, which is defined in admin/mnet/adminlib, checks for changes in RPC functions. Mnet stands for Moodle Network (see http://docs.moodle.org/en/Moodle_Network) and RPC stands for Remote Procedure Calls. Moodle Network is new with 1.8, and it allows multiple computers all running Moodle to communicate with each other. RPC is a protocol that allows computers, possibly running different operating systems (Linux, Windows, etc.) to communicate to the extent that they can remotely call basic operating system procedures in each other (sounds potentially dangerous; watch out for hackers!). It is used by Moodle Network.

The function upgrade_RPC_functions keeps track of RPC functions in modules, authentication routines and enrollment routines by recording the ones it finds in the Moodle database, in tables whose names (after the Moodle table prefix, mdl_ by default) begin "mnet".

That's about all I know from a cursory review of the code and Googling a couple of terms. I hope it is detailed enough for you! wink
