Description

We are having a recurring problem where every few days all the events in the two higest groups (global and course) are rendered "invisible". Seems that all of a sudden they are all "invisible". We have to go into the database and run a SQL statement and mark them all is "visable", but then a few days later, sometimes in the same day, it happens again. It seems to happen about twice a month at least, once at the beginning of the month and once in the middle of the month, but the day is never the same.

I do remember that at one time we cleared out some fields in another table (mdl_course_sections). The fields were the "sequence" and "summary" fields. This was done when we needed to delete all content for the weeks for the year after we advanced the start dates for all the weeks. (We also added an extra week.) I wonder if that had anything to do with it. This is when we lost some parts of the site's main menu and possibly some main site content. At that time we basically went back to a back up we made and re-inserted the "sequence" numbers listed for the main site "course" and that fixed a whole bunch of stuff.

Any ideas. I've seen others report this problem, but I've seen no solution. See links below.

I think this is a issue that Martin should be aware of. This is a major problem on our production site right now. I'm adding Martin to the watch list. Thanks!

Does anyone who are really familiar with calendar code remember where in the code might "reset" the visible field in the MDL_EVENT table from 1 to 0? We have some manually created "course event" that got disappeared but it's really difficult to reproduce. Many thanks!

Hi Wen, sorry I have no idea. I did not find this field in 1.6 and above, so the invisible problem could not possibly affect 1.6 above. I am removing these. Cheers, Yu.

I just thought that if 1.5.x is no longer being maintained with the moodle core team (and the community), then maybe it should be announced somewhere (or included in in the README.TXT in the MOODLE_15_STABLE branch or downloadable zip file, or something)... instead of just abandon it quietly... what do people think? Just my 2 cents...

Anybody may step up and start fixing bugs in any branch he/she wants.

Unfortunately there are not enough people to maintain 1.5.x, 1.6.x, 1.7.x, 1.8.x and finish 1.9.0 while working on 2.0.

  • 1.5.x is not on download page for some time and it is not receiving any fixes at all, anybody who wants to use it should watch 1.6.x for critical bugs and backport it himself/herself
  • 1.6.x is getting only serious security fixes and patches from volunteers
  • 1.7.x was not a good release, anybody using it should consider upgrading to 1.8.x asap
  • 1.8.x current stable, has performance problems
  • 1.9dev - finally should be a version with "long term support"

Most fulltime developers are now working on 1.9 only. Martin is doing all he can to get more developers, but it is very hard to find skilled ppl.

As Petr said, it's not on the download page: http://download.moodle.org/

I've added a note to the README.txt but I doubt anyone will read that...
